It’s pretty useless, I know, but I just made ‘Snake’ game with AGS. Even better, I’ve made it as a scripting module, so basically everyone could use it!
Download:
bare module + demo game source (~40kB)
compiled demo game (with small improvements).
p.s. Music from http://www.harari.net
upd@07-14-2009: the links do not work, I am aware of it and don’t give a damn.
