I am not sure what era or game this is trying to represent, but the Doom- or Quake-like controls work well enough for me. I wasn't able to get very far as even the green room which I take to be the easiest path was a bit tough. The pixelated effect is really cool, but at 2-3 vitality the corridor all blends together. I'd like to see going through all four rooms and upgrading each time to see how it plays out.
