5/5. Didn't have much of a problem except that after a certain point it becomes a giant clusterf-I mean the screen is loaded with airway traffic. Never experienced anything out of the ordinary aka bugs. The only achievements I didn't bother getting are Bona-fide Millionaire and Sky Captain.
I got a(n) A- on hard! My score was 2761713 with a max combo of 160. I scored 257 perfects, 79 greats, and 13 goods. I got only 4 bads and 4 misses! I was playing on 15 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
