The visuals are real nice, somewhere in between a Gameboy Color and a Gameboy Advance game. The controls are mapped a little weird - I would've preferred a WASD option. Screen transitions were a little glitchy in that if I was holding an arrow key down between rooms sometimes you'd get warped to the far side of the new room. Enemy hit boxes felt a little unreliable - especially on the boss. It would be nice if enemies had some chance to drop a health item or something.
