Even after completing it, I'm not quite sure how you're supposed to play it.

I basically kept holding an animal, seeing the line and then scrubbing back a few frames to place it there. I have no clue how you're supposed to know what lane the line will be coming from even if you can get to the sync of music. Now after trying the first level again, I guess they could be just coming in order from left to right always?
The visuals were great! Awesome and stylistic. Dunno if it was just on my end but it performed very badly, especially later on. Like lower than 10 frames per second on the last level. And obviously it doesn't seem that much of a resource hog so must be something weird going on.
