Eat the Whistle
Eat The Whistle is a football game originally released for Amiga in 1999, then made opensource and ported to windows, mac and linux in 2003.
In 2013 I released an heavily customized version for iOS and Android.
The project is still maintained and it's part of the debian repositories.
The game is written in C and uses SDL (www.libsdl.org) as video/input/audio module.
It provides a "simulation" and an "arcade" game mode.
