Glaw

Glaw is not really a game engine but a collection of utilities to write games.

Its core only depend on cl-opengl (without glu or glut) for graphics and cl-openal (without alut) for sound. Source code with examples is available here.

Small games written using glaw include:
 * outbreak: a simple breakout clone
 * kayou: asteroid clone
 * push: on-button game (entry for ILGE2010)
