This is a GBA port of the old 6packman with some changes to suit the new machine, plus entirely new and improved levels, more music, and just general spiffyness. If you have a flash cartridge, you can play it on the real Game Boy Advance, otherwise I'd suggest downloading an emulator (I find VisualBoy Advance to be the best all around). A quick googling will always turn up a copy, and it's free.
Six Pack Man is now up for Download. Here are some screen shots. The game is a run-and-jump screen to screen platform game (a la Montezuma's Revenge) that was heavily inspired by an old Amiga game called PlatMan.
The manual and system requirements are available here
