is a tile-sliding puzzle game that I created in 1998 for Gameboy Color.
I wrote it in C, which I'd taught myself the previous year.
It won third prize in the first "Bung Enterprises Gameboy Coding Competition", and the prize money
covered the cost of the Gameboy Color and cartridge-flashing hardware I'd bought to test it.
The gameplay is fairly similar to Chuzzle
, a game Popcap developed seven years later in 2005
(I don't think they copied or even knew about this game, though!).
You can download Coffee Drop here
, and will need a Gameboy Color emulator
(or a Gameboy Color and the hardware to flash Gameboy Color cartridges) to play it.
