Hey, cool game! I really liked the Gameboy aesthetic! There were a couple of things I noticed, though. The hitboxes are pretty strict, so it's kind of difficult to sneak by enemies. One of the spikes I encountered (third level I think) didn't kill the player. Also, if an enemy hit you twice before you died, the fade-out animation would play twice in a row. (I also think the signs should have been walkable, but that might just be a design choice). Nice work on the game, though. I enjoyed it.
