conceptually interesting, but mechanics could use a bit more polish. My main gripe would be the movement, it's rigid and really easy to get stuck in weird angles. Another problem I run into was the sudden enemy spawn, there's no indication where the enemy spawn unless you already know ahead of time. There would be times when I was just moving through the level and then I seemingly get a game over out of nowhere because I unknowingly walk into an enemy spawn zone as they were spawning in. With a bit of polish, this is quite a neat concept.
