GMC Jam 5 - First Place

Light and dark magicians alike are kept trapped between the mazelike walls of a special prison. The Warden's gift to you enables your escape.

Penitentiary is a puzzle-platformer combining spatial geometry and quick-reflex segments for a mind-bending experience. Invert gravity, slip through solid ground, and make your way to the exit teleporter across nine levels.

This game was created for the GMC Jam #5, where it took home the honorable ranking of First Place. Music by TheFugue was utilized in this project.
