I ran out of ammo and for some reason was never given the menu to buy it beyond that point, so I wasn't able to finish the game, but I had fun!
I found the graphics and engine to be *more or less* within the bounds of the contest, like a higher resolution Wolfenstein. I think I prefer the way it looks after the player takes 1 hp of damage and becomes slightly pixelated.
You have the beginnings of some good sound design, with effects pitched a fifth apart so they will fit in the same key. I think to complete the effect here, you need a song in that key too, with either SC-55 MIDI music or OPL.
