Brasileiro? Legal!

Apart form this very Brazilian title, me translating this announcement into Brazilian Portuguese would be crazy bad, so I'll spare you the annoyance of reading it.

But do you know who is good at translating to Brazilian Portuguese? Our translators! That's why ChromaGun now features subtitles in your favourite Brazilian language!

Did we do good? Did we not? Let us know!

Who Needs Colors?

Dear Chromalovers,

as we all know, the core principle of ChromaGun is based on colors. Hence, the name. (The chroma-part, that is. Not the gun-part. Whatever.)

Colors: They're not for everyone
The problem with a color-based game is, only people who can actually see colors, can play it! Who knew? That means, we're effectively cutting out 8% of the world population. That's almost 600 Million people who can't play ChromaGun! It's a crime! A crime, I tell you!

(Also, dogs are color blind.)

The Big News
That's why we have some great news for all you deuteranopes, protanopes, tritanopes and doges: There's no need for seeing colors while playing ChromaGun anymore! We implemented a new accessibility feature called 'ChromalessGun'! (We're not actually calling it that, I just thought it might be funny). Switching on the new colorblind mode in the settings menu, will make icons appear in the UI, on the gun, droids, walls, ... everything that can be colorized, really.

How it works
The colorblind-icons can be combined, just like colors. That makes it easy to identify color-combinations for the chromatically impaired. And this is what it looks like in the game:

We really hope you enjoy ChromalessGun! If you have anything to say, leave a comment! Let us know what we did wrong, what we did right and what we didn't do at all!

Pixel Maniacs out!

Welcome to ChromaTec’s test lab! You’re here to test our newest, state-of-the-art military-grade color-technology: The ChromaGun (patent pending)! Use it to try and solve our meticulously designed test chambers. The basic principle is as easy as applying it is complex: Exit the chambers via the exit doors. But be weary of the WorkerDroids in charge of maintaining the chambers. They’re not exactly what you and I would call “human friendly”.

Use the ChromaGun to colorize walls and WorkerDroids to progress in the chambers. WorkerDroids are attracted to walls of the same color. Using that mechanic, try to reach the exit door of each chamber. Some doors are more complicated to use than others: They can only be opened using door triggers and only stay open as long as the triggers are occupied.

If all of this sounds like your brain can handle it, congratulations! You’re the perfect candidate for our test chambers!

That being said, welcome and good luck!

ChromaGun is a nice little puzzle game, where you use magnet-like color to pull in magnet-like orbs into a certain area to progress. My copy was kindly sent to me by the developers (thanks for that by the way) because of my YouTube channel, and I would have made a video on it had I not lost the video file. Either way, I recommend you get ChromaGun if you liked Portal 2, but would rather have it with plain colors, and not cool dimension-ish wormholes.

I love puzzle games like this one, and Magrunner, and the Portals. I'm 70 yrs. old and I'm trying to keep my brain sharp. But when the game designers INCLUDE a NECESSITY for DEXTERITY in the game, it really ticks me off. I get really disappointed by the fact that I paid the same price as anyone else, or close to it, but I don't get to finish the game, because my fingers aren't as fast as my brain. This game does just that. I love the whole concept of mixing the colors to open the doors, and even getting the colors in the right orders. It's a cool concept and fun to play and solve the puzzles. BUT here I am running from a fire that my fingers just aren't fast enough to solve the puzzle. Although I know WHAT to do, I can't physically do it. Maybe I could if I did it over and over and over a million times, but I don't care to do that, that's why I bought a PUZZLE game. Maybe I should have waited a while to cool down before I wrote this. I recommend this game for anyone that loves puzzles, AND has the DEXTERITY to solve them!

Chromagun is billed as a first-person action puzzle game, although it starts off focusing mostly on the puzzle aspect and then picks up the pace later on. If you're after a thoughtful, no-pressure game then you'll struggle later on where speed is important.

It's inspired by Portal, with a similar look and narration, but the puzzle mechanic is totally different. Here, it's about painting walls and droids different colours with your paint gun. Droids get pulled towards any surface that's the same colour as them, so you use that fact to move them around the level and position them on pressure pads that open doors.

To add some action, some droids are deadly to the touch and will chase you around the level if there's no coloured surface to pull them in.

Some gameplay from chapter 2, post-tutorial:

The paint-mixing idea is a great basis for setting puzzles, but it feels like they could have done more than just using it to get droids to cling to walls. Particularly because (based on what I've played so far, 3/4 of the way through the game) this is a 3D game that never really uses the third dimension in your puzzle solving.

Like all decent puzzle games, the game intelligently drip-feeds in new elements and teaches you their use, either through direct explanation or letting you discover it for yourself. Chapter 1 is a tutorial with one colour in your gun, Chapter 2 gives you the full three-colour gun and teaches you the art of mixing, while chapter 3 adds killer floor tiles that destroy droids, sometimes to your advantage. Chapter 4 adds walls that remove your paint after a short time. And so on, up to Chapter 8.

But this is a game with a story, and Chapter 4 ends on an action-packed climax ready for an atmospheric Chapter 5. At this point you wonder if the game up to this point was one long tutorial! Beyond this, the puzzles require faster thinking, faster timing and all-round more speed to proceed.

A few puzzles are inelegantly designed, ones that makes you wonder if you found an unintended shortcut or whether the rooms needed a second draft.

For instance, level 4.5 was first one where I was stumped for a while - the solution turned out to be mentally putting together stuff I'd done before, but it also required getting a droid to pass a certain point at a certain time that was annoyingly fiddly - I had already figured things out but spent ages running in circles to get it just right. I couldn't work out if it was me or the game at fault.

But all the puzzles are contained enough to be manageable. It rarely puts a second difficult puzzle after a first within a level (which might mean if you die on the second you'd have to plod all the way through the first again).

So I've been enjoying this, with reservations. I found the early stuff a bit gentle and I rattled through a lot of the game before hitting the real challenge, but it always changed things up before becoming boring. I enjoy the moments of panic and quick-thinking, and solving a puzzle is satisfying. But some of the timing later on is too tight to be fun and gets frustrating. But never mouse-breakingly so!

I nearly didn't buy ChromaGun because I read in another review that the difficulty spiked and the game went from gentle puzzling to demanding serious dexterity. I'm glad I chose to try it anyway. For context, let me explain that I am an average gamer in my late-forties with serious sight issues, and yet I completed the game in around 10 hours with 100% achievements. The puzzles ranged from easy to mildly challenging. The basic mechanic of manipulating droids by changing their colour, or the colour of their surroundings, is a neat one. The devs have borrowed Portal's premise of a guy (or gal) going through test chambers. Critics might say this is unoriginal and I suppose they have a point, but at least it's better than the cheesy 'contestant in a deadly game show' format utilised by several of the other games in this genre. It also means Chromagun's levels are bite-size - some of them take a few seconds to complete once you're figured the solution - so if you screw up it's no hardship to restart and try again. This makes it a good game to boot up whether you have ten minutes to kill or wish to spend a few hours gaming.

To sum up, ChromaGun isn't an ambitious game. The graphics and sound are solid and unpretentious, it's slick and bug-free, and there's a welcome side serving of humour in the voice over. Recommend. 8/10

ChromaGun is a first person puzzle game where you are a test subject that uses colours to solve your way through the ChromaTec testing chambers.

Check out my Quick Review here: https://youtu.be/kfuTC9c-GG4

When I first started playing, I got a Portal vibe from the game, probably because of the testing facility theme, and being immediately armed with a ChromaGun, but that’s about where the similarities between the two games end. Your main objective throughout the game is to open the exit door and move on to the next room, and there isn’t much of a story.

So, you’re in this testing facility, and your gun shoots three primary colours (red, yellow, and blue), and you can also mix colours to form secondary colours orange, green, and violet. You use your ChromaGun to shoot colours onto walls, droids and sometimes on the ground, in order to attract nearby droids of the same colour. By positioning them correctly, you’ll get the doors to open.

  • graphics are simple, but decent (similar to Q.U.B.E. with all the white-walled rooms)
  • sound effects and music are good
  • voice acting for the narrative is done well, and it's amusing at times (similar to Quantum Conundrum with far less dialog)
  • interesting puzzle mechanics with mixing colours is straightforward, but still enjoyable if you aren’t looking for too much of a challenge
  • speedrun mode available

  • puzzles are too easy for those looking for a challenge, which leads to the game being a bit short (some more complex levels or larger rooms where not everything was on the same floor could’ve been neat)
  • the colour brown doesn’t work to attract the brown droids, like the other colours - it seems that it’s intended, but I don’t quite understand the reasoning behind it, since there's no way to undo colours once you shoot them, so if you accidentally turn things brown you might have to restart the level (it’s not a big deal, but still a minor nuisance)
  • small annoyance with the loading screen between levels being before you even get to the door where you have to wait anyway; could also do without the special loading screen
  • some of the voice lines get repeated when you restart the level, which is fine for the most part, as long as you don’t restart too frequently

The game starts off very easy, and it gets slightly more challenging as it progresses, but only a small handful of puzzles near the very end actually made me have to stop and think about what to do. Even then though, it was more of me trying to get the droids in the just right spot by colour changing at the right time, rather than actually having to figure the puzzles out. There are some levels that are timed, where you will burn to death if you mess up, and normally, I’m not usually a big fan of timed events, but these levels easy as well, and just took a couple attempts to solve.

The game took me about 3 hours to complete, and I don’t feel the need to replay it, but there is a speedrun mode available for those who are interested. The gameplay is smooth, and I did enjoy the puzzles even though most of them were pretty easy, but I would have really liked to have had some flexibility in how you can go about solving puzzles, or even just more complex level design to make the game more challenging. If you’re interested in some puzzle gameplay with simple mechanics, you will probably enjoy ChromaGun, but keep in mind that it is a short game, and easier than games like Q.U.B.E. or Portal.

The game has the same feel of portal with a different type of puzzle. That being said, I did have fun. However part of me feels like portal inspired this game, because it was way too similar with the announcer and the white tiles and the gun, ect. Some of the puzzles were not so clear at first and I found my own way to complete them. I wish this game was either longer or had better puzzles. The tedious, run for your life missions, got kind of annoying after a while but it was fine.

buy this game if you miss portal or like puzzle games in general.

Chromagun is a first person puzzler game similar to many such games available on Steam like Portal series, Magnetic: Cage close, Q.U.B.E, etc. You have a paint gun which you have to shoot at droids and walls and combining these two actions you’ll have to trigger switches which open doors to the next level.


The graphics are run of the mill average. Nothing too fancy, the levels are mostly white with little color. This makes sense because the whole game is about coloring the wall panels and the puzzles are based on coloring them correctly, so a white background is the ideal in this case. There aren’t too many graphics options in the game. The game is locked at 60 FPS but I noticed no slowdowns or dips in FPS. The game also features colorblind mode so that’s always a positive.


The game has very slow and relaxing music. The sound effects can be a bit annoying though. The narration is very well done in this game. I was quite impressed with the narrator. It has funny humor as narration just like Portal.


Your main Chromagun can shoot paint in 3 colors, yellow, blue and red. You can combine these colors to make purple, green and orange i.e. yellow and red will make orange etc. You have to go through bunch of tests and unlock doors to open new levels. To open doors there are switches in each level. There can be more than one switch and more than one door as well. The switches correspond to their respective doors and this is represented by a wire on the ground which is color coded. So if you see a purple wire going out from a switch you just follow it and it’ll tell you which door this switch will open.

To activate switches you have to get these droids to move on top of them. You can paint the droids and certain types of wall panels. The droid will be attracted to the same colored wall panel and if there are 2 or more of the same color wall panels, the droid will stay in the middle of these. E.G if there are 5 panels of blue colors right next to each other, the blue painted droid will go to the wall and stand in front of the 3rd blue wall panel. If the number is even, the droid will stay in-between the 3rd and 4th panel.

There are 2 types of droids, normal ones and spiked ones. The normal ones don’t move unless you paint a wall near them with the same color they are. The spiked ones however, once you paint them, they get triggered and they follow you around and hurt you and eventually kill you. This can be stopped by luring them next to the wall that is same color as these droids. So, you have to make use of this to solve puzzles.

A short gameplay video can be found below:




If you’re into first person puzzle games similar to Portal, Q.U.B.E, Magnetic: Cage closed etc. then this game is right up your alley. It’s got enough content for its price and in my opinion and should keep you entertained for 4-5 hours easily. If you think that’s not enough you can always wait for the next big sale and pick it up. The game has some awesome narration as well which can be entertaining.

A First Person Adventure Puzzle Game
+ Many similarities to Portal. You are in a test lab as a random participant chosen to test some new military grade color morphing gun.
+ A pretty comical narrator talking through intercom (I think) who watches and follows you throughout the game through various cameras and makes fun of you from time to time.
+ The gameplay is pretty fun and unique. You mainly go through a series of rooms which each have a puzzle to solve. The main mechanic involves painting hovering balls or "droids" and then painting a wall the same color which will attract the droid to the wall...generally to press a switch to open a door of some sort. Later you being to combine colors in every increasingly difficult puzzle challenges.
+ Visually the game very nice with a very clean test-lab asethetic.
+ The puzzles gradually increase in difficulty and can be quite challenging to solve....just be sure to bring a color wheel if you've never taken an art class ;)

- I wish the narrator was "more involved". I wish he would have spoke more often, and it would have been nice if he provided some hints when you got stuck. He's honestly the most charming part about the game, and really helps push the player forward although he's a bit absent through many parts.
- The environment / puzzles got a bit repetitive for me after a short while. It felt like a never-ending labryinth, and I kept asking myself "will I ever get out of here?" It really needed some more events to change up the pace and scenery.

To preface this. It isn't going to be a review, but more of request for future content. I've completed the game and i had a blast. it was refreshing to play another portalesq game. The commentary was hillarious and the gameplay while a bit easy in the beginning ramped up to a fun and chalenging later chapters. My request is that there eventually either add dlc that adds more levels that are more difficult. Or create a map creator similar to what portal 2 had and allow the community to create maps. This would not only allow new content for players to continue playing this awesome game, but after a editor would be created it would make less work for the Devs to create new content. I sincerely hope this game recieves frequent updates becuase i love it.

It follows a similar style to the paragon title of portal, but with it's own choice of puzzle mechanic. However, it fails to caputure the charm and creativity of it's insparation title. It's colour matching mechanic isn't fun, coming off as the slightly educated version of a slow game of Bop-it. The rooms are very flat and uninteresting to look at, and the intercom voice comes off as harsh rather than comidically savage. I can hoestly say that this is one unrefundable game I wish I could return.

This is one of those games were you think 'How hard can it be?' then when you start getting into the puzzles and getting owned by spikey balls from hell, you wonder 'I can't be this stupid'.

I had the pleasure of playing this game for free and I would definately recommend this to any puzzle loving gamer out there. With notes of The Stanley Parable and Portal, this is game worth your time.

I also did a video of me failing, so please feel free to check it out https://www.youtube.com/watch?v=k0JnDxz9rKA

I finally finished the entire game, and did a full walkthrough/let's play of this game on my channel.
Plus, I've earned all the achievements.

Anyways, I wish to thank all of the people who made this game, and with that, come with my honest opinion, so people can find this helpful, and as well, tell the people at Pixel Maniacs what I think.

Despite I got this for free from the company, I don't believe that should effect my opinion.
The price should be lowered, since I can't see it being worth 13 Euros, when you can complete the entire game within a short period of time, around the 10 Euros would be more fitting.

I truly enjoyed the concept, the idea of a puzzle game, which involves colors, was something that I haven't tried before, and that was truly something different, than what I normally play.
However, the game did seem quite short, and it has it's few moments that can be tricky. The only hard times, are when you're forced to make a wild guess. I believe that the game could've easily be longer, and a lot more challenging.

I must say, that I enjoyed the narrator and his evil voice, giving you some kind of hints now and then, but you barely heard from him later on in the game.

What I pretty much asked for, is more gameplay, and a greater challenge as you progress.
With all this said, the game is not bad at all, it's worth playing, but it should be for a smaller price then, since it is as short, as it is.

Big applause to Pixel Maniacs for this nice game. =)
