Great game, heres some tips on how to survive
level 1: i cant give you tips for this, its just to easy if you have any notice to the rhythm you will be able to predict when to jump.
level 2: Stay in the right corner of the screen, only 1-2 blocks will fall there per time you play.
level 3: I just stay at the top and only move steps apart from it, then move back.
FINAL BOSS!!!: wait for him to come to you then switch to the other sides until he turns red, then you have him, you must repeat this 3 times and he gets new powers.
