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 7 Released - LEVEL EDITOR



The most requested feature EVER is finally here: the LEVEL EDITOR! After one year from the release of the game on Early Access, I thought it was about time to allow people to create their own content. I wanted to create a level editor in line with the minimalistic style of the game, yet powerful and easy to use. And I think the current one hits all of these three! :D

The level editor allows to:

  • Create celestial bodies. There are several types of celestial bodies you can create within the editor. They are all labelled as planets, even though their appearance and properties will changes according to their size. The editor currently supports asteroids, rock planets, gas giants and stars. And of course, their anti-gravity counterparts...

  • Design orbital mechanics. 0RBITALIS is a game about gravity. And the editor has all the tools you need to decide how what is orbiting around what. There is also a nice support for group moving, which allows to relocate celestial bodies retaining their relative angles and positions. In addition, you have full control over the angular momentum of all of your celestial bodies.

  • Create probes and anti-probes. Advanced levels in 0RBITALIS allow you to control several probes at once. The editor gives you the same power ...and much more. There is a feature which is unique to the editor and not available in any other level of the game. ANTI PROBES! You can have probes with negative mass, which will be attracted to anti-gravity and repelled by the good 'ol Newtonian one. Oh, did I forget to mention that they are blue? :D

  • Share your creations on the Steam Workshop. You can share all of your levels with the Steam Workshop. It is also accessible directly from within the game, so that you can browse and subscribe to other levels without even closing or minimising 0RBITALIS. All the levels are automatically names with a star-y name; you can change that from the Steam Workshop.

Of course, there are lot of things which are still missing. For instance, you cannot vote levels ...yet.

As always, thank you so much to all the players who followed 0RBITALIS since Alpha 1. Your support has been amazing and I hope you'll like this new update.

Funny or better to say mind blowing (like to kill me now !!! situation) game.

Point is to set your "satellite" orbits to low orbite of combination of lvl planets and their circulars as longest as you can.

Funny and hard game ... frustrating ... especially when you cannot set satellite to orbit for more then 4-8 seconds. Very frustrating ... but there is even greater price when you succeed and beat let say more then 5 minutes.

Enjoy ... really worth any price (best in sale) . One of the best pixel games ever.

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.

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.

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.

This game is soothing and pleasant, and the spacey vibe is definite fun. Gameplay mechanics are reasonably intuitive after not much time. Cool retro feel, nice music and presentation, and a great game to play while other things are going on. If there's one drawback, my system seems to run the game a little laggy in parts, but no doubt further improvements will help that situation.

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!

Spirograph, The Game!
Seriously though, it's a fairly intriguing game.

The entirety of the game revolves (hah, wasn't intending that) around using gravity to complete an objective depending on the stage. These objectives vary from just staying alive and not crashing for a specific period of time, to flying through specific points on the map (using the gravity of static or moving bodies), to maintaining proximity to specific gravitational bodies.

The UI of the main menu leaves a bit to be desired, favoring artistic beauty over simplicity/clarity; from what I can infer, the idea is a pseudo-3D look, but in reality it all just looks blurry and out-of-focus. However, the actual gameplay doesn't suffer from these problems.

Another drawback of the game is that it is very CPU intensive. I currently have a Intel G3258 CPU in my computer that I've over-clocked, and any time I even attempt to go over minimum quality settings, my computer starts to noticably chug.

At the end of the day though, I had a quite enjoyable time. The mechanics are SPOT-ON and, although it seems the dev missed the mark when it came to the menus, the artistry of the actual gameplay is quite mezmerising at times. As long as you're not expecting anything genre-defining or ground-breaking (as most levels are pretty much variations-on-a-theme), you should have a pretty good time!

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.

More luck than puzzle and "gravity simulator" is far from accurate. How is the gravity inacurrate?
- orbits decay automatically, as if you are experiencing atmospheric drag which doesn't fit the story
- celestial bodies pull you to WHERE THEY WILL BE. It should be pulling you always to its current position
- there is no aerobraking when you are deep in a planet's atmosphere. you either hit the planet or accelerate around it
- super high gravitational constant

If this game had accurate gravity it would be far too easy. Try NOT landing on a planet in KSP. Yeahhh that's how most of my KSP missions end up.

This game is a casual time waster for about 30-60mins. Probably better off as a phone app.

Early Access Review
This isn't really a "puzzle" game with any discernible mechanics. Most of the gameplay consists of trial and error.

I only played the first handful of levels (which should have been showing me the core game mechanics) but all I experienced was randomly clicking on the screen once, waiting, and seeing what happens...usually resulting in repetition. Since you have to keep your ship "in orbit" for a certain amount of time, the amount of waiting time after each click while watching the resulting animation is far too long. The game has a lot in common with the annoying component of Space Badgers.

For a game that is all about gravity, we aren't even given the most basic information (such as the relative masses of the various planets/stars or their relative distances from one another). The concept is solid, but the game does nothing to actually follow up on it other than a mere visual presentation (which is apparently not graphically optimized, but I have a brand new system so I couldn't tell).

A puzzle game implies some form of logical structure or thinking involved. Perhaps it is the games presentation that is lacking and I simply missed it, but as another reviewer said, this felt like "a glorified screen saver."

Pass.

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 definitely just a trial and error simulator. It is very difficult to find a strategy that will work, and you're not "solving a puzzle" with each level. Are you going to get lucky so that your object stays within the prescribed area? It may or may not have a center of gravity or be centered around the center of gravity. So yes, this is luck.

One additional gripe I have is about the spelling of the name. The zero at front guarantees that they are listed first alphabetically in almost all lists. It does, however, make the game very difficult to find in your games list. Zerorbitalis.

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.

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.

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.)
