So, finally, I decided to give OSGG a slight round of hacking.
I added glorious instructions on both the editor and the game.
And I also got it compiled for Windows computers (but only the game, not the launcher, so windows users will have to start it from a command-prompt if they want to use non-default parameters).
I'll likely add some more levels in the future, maybe during a twitch session :)
Anyway, builds are available on sourceforge.net
and in contigrator
Grab the .tar.bz2 for source+linux and, the .zip for windows.
