Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“0RBITALIS is an experimental game, surely diverse from the majority of indie titles you might have played before. For this reason, the input of its community -- your input! -- is necessary to shape it into the gravity puzzler you've always wanted to play.”

Approximately how long will this game be in Early Access?

“A final release date has not been announced yet. The game is in constant evolution and we're happy to keep on going until we will feel 0RBITALIS is ready, both in terms of content and aesthetic.”

How is the full version planned to differ from the Early Access version?

“Every update expands the Universe of 0RBITALIS, adding new levels and extra challenges. We are working to bring new features into the game, some of them truly unique to 0RBITALIS. Planned features include histograms for a more meaningful score visualisation, cursors ghosts from the best players to advice you on launch strategies, procedurally generated levels for daily challenges, a proper menu and UI system, and 150+ missions across different constellations. And maybe, a level editor...”

What is the current state of the Early Access version?

“We're launching 0RBITALIS onto Early Access with a variety of gravity-based mechanics, across 50+ unique levels and secret challenges. Surviving, exploring, landing, destroying ...all you need is a click. The game visualise leaderboards in a novel and unique way, encouraging the player and his friends to keep improving their scores. Even in Early Access, 0RBITALIS is already a beautiful journey into the infinite complexity of gravitational forces.”

Will the game be priced differently during and after Early Access?

“Given the fact that 0RBITALIS is still in Early Access, all the players who are willing to support it before its final release are offered a price reduction.”

How are you planning on involving the Community in your development process?

“Every new feature in 0RBITALIS is announced and discussed with the community, where suggestions and critiques are always taken into consideration. Every update balances new and existing levels, according to players' feedback, in order to maximise the game experience. Moreover, the developer team is doing its best to reply to all the questions posted in the forum. You ask it ...we answer it!”

Alpha 6 Released

The new update for 0RBITALIS has finally arrived, and is bringing the game closer to its final form!

  • Daily challenges: If you are familiar with games such as Spelunky, you'll know that they have a featured called daily challenge. A new level is procedurally generated every day, in such a way that it will be the same for all the players across the world. 0RBITALIS has now such a feature and it can be accessed directly from the title screen.

    At the moment, a daily system can be chosen out of these four:

    • Standard systems: Similar to the first level of the game with a single star and multiple planets orbiting around it.

    • Multiple systems: Several stars, orbiting around each other. They have a high chance of turning into pulsars.

    • Planetary graveyards: Big asteroids orbiting in a dead system. Much like Koronis

    • Asteroid fields: Stranded asteroids flying in the interstellar medium. Similar to Sedna.

    Pulsars and missions with multiple probes can occur. This will give to players who have not unlocked advanced constellations yet to have a glimpse to more interesting mechanics.

    I've been talking about this feature for a long time: I'm very happy it has been included and I really need your help to make it better. When a level is procedurally generated, there is always a chance it won't be very ...desirable. With a gravity-based game like 0RBITALIS, avoiding this is a very challenging task. For this reason, the current update includes only four different types of systems which can be generated. I'll collect your feedbacks during these weeks and tweak them accordingly. When happy, more type of systems will be available. I'd love to use this feature to generate bizarre, crazy levels like Tesla or Soundself...

  • New interface: The game has a new title screen, which is starting to look like a real menu. There have been lot of improvements to make the navigation between levels easier. That's how:

    • Title screen: It links directly to the last unsolved level, to the starmap and to the daily level.

    • ESC button: After so many requests, 0RBITALIS FINALLY uses the ESC button. Its effect depends on the context:
      • Title screen: Toggles the fullscreen mode.
      • Starchart: Returns to the title screen.
      • In game: Pops up the leaderboard screen.
      • Leaderboard screen: Returns to the starchart.

    • Mouse lag: YES! The long lasting issue which affects so many users has been finally fixed! Now the mouse clicks do not depends any more on the framerate... which make the control so much responsive. The game will still run slow on outdated machines, so you might want to select a lower quality with [Q] if that's your case.

  • New music: It is a tradition that every update brings new music pieces. Alpha 6 is not an exception, including new tracks from the amazing Doseone! They are all featured in daily challenges, so let's go play them. NOW!
I'm already working on the next update. Hopefully you won't have to wait that long before Alpha 7. Oh, and if you allow me some spoilers... ...there might be a level editor.... But shhh... don't tell anyone! :D

Early Access Review
Did you as a kid marvel at the science behind the NASA Voyager missions. The simple beauty of the slingshot physics as gravity affects the path of the craft. Well this game takes that concept and runs with it. This title is very much in the spirit of other planetary physics games. Think Bit Generations Orbital, but the core gameplay honed to a razors edge.

The opening missions challenge you to keep your satellite in the planetary system for a set time. All with one click of the mouse. Before you launch your craft you are given initial visual flight paths guides. At the start, trial and error plays a part. But this won’t help as complexity of the systems ramps up. Like all great gameplay ideas, what at first seems a throwaway casual experience becomes oddly compelling and addictive. The daily challenge adds an extra layer of competition if you manage to battle through all the pre made content.

Well worth a look.

Personally I didn't find 0RBITALIS that interesting. It's a nice time-killer but to me it seemed that the game is more luck than gravity. Also I find it boring because it's a trial and error and no real goal. If oyu really want to give it a shot (I don't recommend it) wait till it's on sale.

This is early access? Wow! I randomly picked it out of my guilty stack of unplayed games and am very impressed. Great sound, great puzzles, and addictive. If you like casual puzzle games, then this physics based puzzler is for you!

Early Access Review
The cunningly-titled 0RBITALIS (sure to be at the top of your games list) is an intriguing puzzle game for those who want something a little different. Billed as a gravity simulator, the premise is to launch a satellite into orbit for long enough so you can reach the next level. Sounds simple enough? Using a mouse, you can select your speed and launch path and you have to use the gravitational pull of stars and other celestial bodies to extend your flight time without leaving the play area or colliding with something.

Usefully, the mouse cursor position of your previous attempt is shown on-screen so you can tweak your next launch. There are no lives, no time limit until launch so you can take your time: this is advisable. One joy of this game is that it encourages experimentation - you can see the flight path up to a limited point. There is no single solution, which encourages you to make several different attempts. Your times are saved in a leaderboard and there are daily puzzles to play around with.

Because of the terribly complicated calculations of gravitational gradients and the like, the programmer had to use Adobe AIR in order to set out to do what he has done, so the game can be quite processor intensive. Fortunately, there are quite a few options to lose some of the background detail and this did the job just fine for my middle-of-the-range PC.

It could well be time to introduce an addition to Newton's laws of motion: the classical mechanics of this game can be addictive but that is no 'constellation' if you crash and burn. I speak with gravitas about this possibility.

Early Access Review
This is a great little game. The way the physics works out is really captivating and has you crossing your fingers that you have just enough velocity, or that the gravitational pull of certain objects is just strong enough. Plus, there are no right answers. Everything is moving. The puzzles aren't static. Timing is everything.

The only things that drive me crazy in this current iteration are A) it runs in windowed mode, with the bottom part of the window cut off (if there are options somewhere to fix this, I can't see them), and B) on my laptop at least (haven't installed on my desktop) the menus are really sluggish. The gameplay itself is pretty smooth, oddly enough. Just the menus hold it back. Of course, this game my be at the limit of what my laptop can handle.

All in all, though, a solid game. More addictive and enjoyable than I would have anticipated from such a simple premise.

This is a fun pick up and play arcade game where the goal is to shoot a projectile/satellite/I don't know in a star system and try to make it stay intact long enough to finish the level.. It's a physics puzzle game about gravity. The gravity simulation works well and it has a very nice minimalistic presentation. In addition to simply solving the levels you can try for a high score by keeping your satellite in orbit for as long as possible.

The dev plans to add a daily challenge which is always nice.. Will update review once out of Early Access, but if you enjoy these sorts of games don't worry about it being in Early Access.

A fun little game, very simple, it has no story or anything but is is fun and kind of hypnotizing to watch things orbit around each other. it's also good becasue you get a billion coupons for 50% off this game all the time, so if you have one of those coupons, don't hesitate to buy it.

0RBITALIS considering it is only in Alpha is very well made game. The "Game" is there and is ready to play.

Good purchase if you want a fun physics game to pick up and play for short periods of time.

A really fantastic minimalist game.

A mix of spatial reasoning, trial and error, and dumb luck, it's certainly worth checking out. With a solid difficulty curve and lots of variation you'll get a decent few hours entertainment out of it, perhaps more.

Early Access Review
0rbitalis takes a deceptively simple game idea and creates something complex and fun out of it through a large variety of levels with various layers of difficulty.

The basic concept of the game is gravity and taking it into account while clearing a number of different tasks depending on the level. In the initial levels you are attempting to maintain your Probe's orbit around various celestial bodies, while later you have to hold the orbit in specific areas or crash your probe into specific targets. As you go through the game, it gets more difficult with different obstacles that will throw you for a loop. A nice plus is that there is a leaderboard to compare your times to other plays to see what is possible and strive to do better.

My minor complaints of the game would be a more apparent UI and a little more musical variety would be nice.

Definitely worth checking out.

This game is fantastic when the player is under the influence of conciousness-enhancing substances. You're gonna shoot your planetary body into perfect orbits and just appreciate the beauty that gravity is. I'm still watching the first level, expect me to be #1 on the Leaderboard there.
But yes, let's continue being honest and say that this is not a real game yet. You have no options beside fullscreen (with 2 large black bars left and right if you're on a 16:9 screen) and windowed by pressing F. It's launched in some sort of video player. So, I hope they'll build some sort of engine around it to at least look like a real game.
But yeah, definitely enjoying the first level so far, already worth the purchase (like 2€ or so).

Early Access Review
Very nice game! Pretty addictive, great physics, innovative challenges.

Here are my suggestions:

1. Keep the background music playing while orbiting. No music while watching the particle orbiting feels kind of empty. Maybe the music could also change depending on the action. Example: goes faster as the particle goes faster, or as the time passes; maybe with a special effect when a personal best is reached

2. Put the timer counting somewhere on the screen right after firing. It will be much more thrilling to see the timer going while orbiting than waiting for the round to finish to know the end time

3. If a level has been completed, that the player replays the level to try to have a better time and fails miserably (i.e. before the required time to pass is fulfilled), he shouldn't be treated with a round restart as if he had never passed the level (therefore not seeing the leaderboard and not having the option to go to the next level). He should be brought to the leaderboard so he can go to the next level if he wants as he may have failed now but he beat the level already and therefore has the right to go to the next level if he wants

4. An outer ring that shows where is the limit before the particle is considered lost in space. It would be more thrilling to see the particle getting closer and closer of the ring limit, hoping another particle will have enough attraction to bring it back into the game

5. Of course, achievements. When achievements are implemented, if a player by his previous games has fulfilled one, it should be granted immediately (example: make it #1 on a leaderboard)

6. More levels with specific goals to accomplish, like the last levels where you have to touch lines to make the progress bar move in order to pass the level

7. Nice to have, better graphics, especially better effects (flash, blur, etc.)

There's some things in life that are evil. Gravity is one of those things. Yes, it keeps you from floating away, and it makes going to the bathroom a whole lot less disturbing, but I'm telling you - it's the force of the devil. Don't agree? Think about it - how many times have you dropped something on your foot, or fallen down stairs? Exactly! Without gravity, this would not happen!

So, imagine my evil laugh when I discovered a game which would allow me to defeat gravity, and better - use it to fly my little spacetriangle further, and longer in the galaxy of 0RBITALIS.

This game, is unique. And that gives it a great charm - added to by the really nice art style and audio.

I like puzzle games, and I like space - this game has both things in abundance. The puzzle elements are challenging but not impossible, which is great.

I'd recommend this game to anyone looking for something a bit different, yet strangely familiar in feel, or who like a challenge.

Also, if like me you are suspicious of gravity, then it's a must play!

Early Access Review:

After playing 2 hours from it, it is a fun game, and I got more enjoyment gameplay time than its money worth. The early access might make it a little slow and rough around the edges in term of load time and the click respond, however, it is a more educational version of tank and canon projectile in a 2D setting type of game. So far in the 2 hours of gameplay time, I encountered few interesting physics such as insert in orbit or free from orbit or hit targets, etc.

I highly recommend getting it even in its current version if you like this type of games. It is very simple, no story, and very minimalistic, but great gameplay, good theme, and good price.

I wonder what other features might be added later on. Review will be updated if necessary.
