Pong GBA is a clone of Pong for the Gameboy Advance created in 24 hours using DevKit Advance during Lincoln Hack 2016. It is written in C and is less than 24kb in size.
The aim is to keep the ball in play for longer than your opponent. Player 1 uses the up and down DPAD keys to move their paddle, Player 2 uses the A,B keys. When one player wins a round the screen will turn their colour and a bar will be added to their score (top of screen). When one player wins 3 rounds the screen will flash their colour 3 times to signify a win and return to the menu, allowing another game to start.
