Space Ava 201

Space Ava 201: Quantum Field Theory is a single-player puzzle-adventure game for the TurboGrafx-CD.  It features multiple turn-based gameplay styles, a huge array of levels, and a colorful cast of characters who travel across galaxies in order to save the world and reconnect with a lost friend.

Space Ava 201 requires the Super System Card, a PC Engine Duo, a Turbo Duo, or some other compatible system, or it can also be played on an appropriately-configured emulator. Enhancements are available when run on the SuperGrafx or using the Arcade Card, but neither are required to enjoy the game.
