yo domino if your doing a medium level theres a lvl bar at the bottom check all the weaknesses flying lvls and respect to fit that level this should help
If you dont know why you're not getting perfects here some reasons:
1. you missed a note
2. just cause you got rock or godly for the whole song does not mean you got a perfect you could have started button mashing giving you -10 points that you need
3. You did not hold a note all the way
hope that helps
Lady's and Gentlemen... This by far the worst thing-thing ive played sitting in a room for 10mins beating people with a stick is not thing-thing nor is a cluter of weapons and not having a health bar its hard to tell with there blood already being splattered on the walls... also the guns are great but if you shoot them too fast (by clicking rapidly) your charater lags and wont respond when you fight the helicopter which is the most boring boss fight you arm dissapears off the screen ( go ahead try it) now I hope the arena is gonna be a better version
