Not bad. The fighting mechanics works pretty well once you get used to it. I never did manage to figure out the tip about walking in circles improving aiming, but I didn't have much trouble with aiming regardless.
I guess maybe I beat the game? I reached a staircase - although I couldn't do anything with it. Replayed just in case there was a bug, same thing, nothing happens at the staircase. I also managed to get stuck inside a door once, but I couldn't reproduce, so can't tell you much more than that. And there's a couple minor clipping problems with slimes getting stuck in walls, but I'm not sure I have a good reproduce there either.
Also, with that fighting mechanic you didn't call it Tongue Fu?
