took e... 20 minutes..? just go slowly and it shall be all right.
also note that after the first bar of music (when it appears to loop) it'll change scinary, and then after the next bar it'll launch some cubes to jump over, and for me i just stood in the same place when the cube attacks.
so, TL;DR version: listen to the music, and when the background changes stand in the center.
Can i suggest that the player can also win by drawing the object correctly on the grid? on level 2 for instance, i know it's in a straight vertical line, and it has gaps in the line, but i can't think of what it would be.
