A lot of fun to play. The redness that happens when you start running out of time was actually kind of terrifying, like a Yume Nikki sort of style, maybe if you continue it you could add some weird enemies. Definitely needed more though, I liked the level design though. You should also maybe have it so you can get multiple weapons. All the guns are fun but I think it would be cool to be able to switch between them, and obviously with more enemy variety.
