It’s amazing! It’s wonderful! It has potatoes.
Get it here. Uses C++ and SDL. Written & compiled in MSVC++ 2008 Express edition. MS Paint & GIMP for graphics. SFXr & Musagi for the sound & music that didn’t make it in.
Note: this is the Debug build because for some reason the Release build refuses to compile.
EDIT: See new post (http://www.ludumdare.com/compo/2009/01/11/balloon-game-update) for version that should actually work.
