Really liked the art, the game felt very cohesive! I got stuck in the first hallway for a while, and the game ended up getting really slow (I think a million enemies eventually spawned in other areas of the map). It might be good to have a cap on the number of enemies, or only render them if they would be on screen. My second play through I ran through the hallway right away, and had a fun experience running around the map. Well done!
