Pretty nice spin on roguelikes! It has a gentle learning curve along with a LOT of blood and an exciting escalation to the soundtrack as your HP falls. I didn't get too far (I hope there's health potion somewhere!).
That said, it's a bit tough to combine real-time battle with aiming the mouse pointer on the tiny characters. I could zoom the browser before gameplay and see better, though the game seems to want a fixed resolution, making parts of the screen scrolled off-view. None of that was game breaking, though, just needs a more practiced hand.
I'd recommend using Chrome over FF (or providing native builds), since the audio tends to get stuttery on web for me.
Hope to see more of this after the jam!
