AdaGate
3D OpenGL dungeon game using Ada: a tribute to Narbacular Drop
AdaGate is a kid-friendly 3D sokoban puzzle game within a Stargate / Portal fantasy setting. It is a great example of modern OpenGL programming using the Ada programming language. It runs on Windows, OSX, or Linux.
While searching a remote south-seas atoll for remnants of a lost American heroine, a stargate kawoosh lures you into 4 strange dungeons. Escape will require the logical rearrangement of weird power cells [ZPMs] that roll in only two directions. Shoot your portal guns at the dungeon walls to configure 2 escape portals, but in order to activate them, all of the ZPMs must be bumped onto their sockets. But beware: you can only PUSH the ZPMs, so you will fail if you roll one into a corner or against a wall. But don't worry, cheating is pretty easy ; )
The proper command to extract the archive and maintain the directory structure is "7z x filename".
