I would really really want to like your game, I liked the idea and concept, I like a good rhythm game and I see there is great potential to your game, but this just missed the mark on being a rhythm game. Anything, and I mean anything like just a simple beat would helps greatly in tapping the correct beat while I am thinking about traps and such. If that's in place I would see this game going somewhere.
Sorry for the harsh words but I'd really want this game to be good, so I guess keep up the good work!
