I like how the intensity builds up. It starts off slow, and gets more intense as the song progresses. The gameplay is fun, but it could be a little more readable; I died multiple times as a result of portal clusters where I didn't realize what all was happening. The ending also felt kinda sudden; it just decides to stop at what feels like a random point in the song. Perhaps this was due to the object limit, but it still feels a little awkward.
