Change gravity direction using the arrow keys. Avoid red colour. Get to the green dots to go a level up. R puts you back to beginning of current level. Press L to skip a level.
This is a game I intended to finish, but have never got to, so here it is! All levels are beatable. There is a better game with a similar concept coming soon (ish). You can favourite and give a love-it if you like the game. Please do not spam the comments.
