I agree with the other comments- good concept but needs some work. The bugs with the keyboard and scoring are annoying, and the ability to restart just one level would be nice. Also, adding some way to judge where the shot is going to be heading would be nice. Good concept, but only a 2 or 3 star game right now. if you fixed those issues and tweaked it a little (maybe add a storyline?) it would be a good 4 or 5 star one.
I got a(n) A+ on medium! My score was 4137600 with a max combo of 355. I scored 267 perfects, 87 greats, and 1 goods. I got only 0 bads and 0 misses! I was playing on 5 speed and had 0 crazy options on. Great game, I like it! Play it here: http://www.thorgaming.com/games/3926/feel-the-beat.html
