It is a sandbox game, based on physics. The game aim is to make contact red object with green object. You can use various objects, solid, wire (rope), and bendable objects. Gravitation will help you.
very very good game
I just installed this game of Fedora 13. It's a brilliant little game! On README file it said that libSDL is needed, among other packages. Actually, I had to install both SDL-devel and SDL_mixer-devel for it to build. I had SDL-1.2.14-8 package already installed and it was not enough. I hope this helps to Fedora users. Definitely give it a try! My compliments to the game creator.
A great game !
