The level design are too claustrophobic for my liking(or more checkpoints), but other wise this is a great Halloween themed game.
The enemies react differently depending on the lamp, creating the need for back and forth. Each level has it's own unique visual set piece, but the goal always situated at the corners, and the "Keys" always situated at the middle helped reign in the chaos.
As your first officially submitted game, you have something very special in your hands.
