AdaGate

AdaGate is a 3D sokoban puzzle game within a Stargate / Portal fantasy setting. It is an elaborate example of modern OpenGL programming using the Ada language that runs on Windows, OSX, and GNU/Linux.

While searching a remote south-seas atoll for remnants of a lost American heroine, a nearly operational stargate beckons.  Transported into strange dungeons, escape will require pushing every ZPM power cell onto a socket to power up the portal system. Then, blast your two portal guns at the walls and escape through the resulting wormhole.

Escape all 4 dungeons and the level of difficulty is increased for your next adventure.
