Space Station 8 is a Micro Platformer created in 72 hours for Ludum Dare 49 based on a game I used to play on my original Macintosh called Spacestation Pheta. Space Station 8 is also heavily inspired by Bitsy and my Fantasy Console, Pixel Vision 8, which I used to create the game.
The goal of Space Station 8 is to escape before you run out of oxygen. To do that, you will need to navigate the level, find the key, and make it to the exit in time. Each level is self-contained, and you are scored based on your ability to complete it within the amounted time and lives. There are also some prized gems you may want to collect on your way out while avoiding aliens and other deadly obstacles like spikes.

Like the original game this is based on, there is a built-in map editor. In fact, there are no pre-made maps at all! The twist is that I lost them after space junk hit the station, so I need everyone's help to make new ones.

Once you are happy with a level, you can share it with someone else by sending them the map.spacestation8.png file. There are several ways to do this. You can attach it in the comments, send it directly to them, or file a ticket on GitHub and include it there.

As you can see, a map is comprised of a 20 x 17 tile grid where each tile is 8 x 8 pixels. The top row is ignored, and for map images that are 142 pixels high, the last two rows (18 and 19) are used for the game's sprites.
There are 40 sprites which you can also modify if you want to reskin the game. Each sprite is fixed to a corresponding element in the game, so while you can re-skin the graphics, you will not make new ones or change the internal sprite mapping.
Come give the game a try and submit your own levels in the comments for others to play!
