This is a great little rogue-like, had some fun with it although it is also quite challenging (I never seem to be particularly good at these kinds of things). The scenery and sound fit together really quite nicely. The menuing and main screen feel a little less polished, i'd really think through those first few visuals and really punch them up.
One easy note is that i found the control scheme didn't really match how i wanted to control it - adding the ability to remap controls to different buttons isn't too much of a lift, and would really help the access to folks with different machines / layouts.
