Hmmm. There was no indication of what the controls were (until you interact with the first sign), but that required you to use a control you weren't told about. The sprites looked a lot like programmer art and colors used made it hard to gauge the depth of the objects. An example of this is that the Brown walls looked like a flat path, but they were actually a wall.

Another thing, you aren't able to quit the game unless you go to the exit stairs. This is a bad design choice -- the game should be able to quit the game whenever they like.

The game concept was pretty cool though. Please don't take this review too seriously =)
