It was awesome that the maze was always moving and changing, the requirement to use Q/E to rotate made it feel kinda tense, and the map was very helpful. With more interesting art, more levels and varied enemies (perhaps there could be some enemies that are static, some that patrol, some that teleport randomly, some that shoot slow-moving projectiles when the character steps onto the same plane, etc.) this game could definitely scale into a full release.
P.S. I love the win screen, that was funny.
