I have been coding a lot in gamemaker, but I have never really released anything, Atm I have quite a few projects running, but I am not working as much on them as I would have hoped for.
have you thought about making square "torus" planets, and just drawing them like if they were spherical?
You get a code when buying the game, this code can be entered in steam to activate the game over steam, the game though can't be bought over steam yet.
This gamemode is dead (ickylevel isn't working on it anymore)
He is working on making it into a separate game though.
