Good first attempt. It's a nice way to kill a few minutes, but overall it's your generic dungeon crawler. Fairly easy, with an emphasis on ammo conservation. The enemies are slow moving, making it very little of a challenge. Graphics are rudimentary and neutral, and there is no music, unfortunately.

There was one massive bug though. I think on the second level you were going for some sort of multi-story rune, which would have been great if the engine wasn't backwards. Walking into a room, I was confronted by the overlay turning on, essentially blinding me... then I died after being unable to see anything anymore.
