I thought the animating and controls were pretty well done - a little slow to respond, but I don't know how to help with that. I thought climbing was broken for a bit but eventually had a little more luck. The enemies were running at me but not attacking for a while. Eventually I got one to attack me and I got a crash, so maybe it was better that I just mowed them down for a while.
I really liked the menu - it was neat that A and D adjusted the volume slider while playing, and I could just close the menu by clicking. It let me do the whole experience without stopping or taking a break!
