Giving it a 4.5 because of how frequently it started crashing before even starting level 26.
It's already hard, and given that it actually plays like 1/4 of the time is making this really frustrating.
Aside that, great game, have most of the achievements now.

I kind of liked it.
It is not perfect, but I'd really give a 4.5 just if the vocals were a little louder.

I was thinking the song was about to end, but then the best part at 2:03 started, awesome stuff!

It's good, especially the beginning, but it's a bit too long, could use an ending too.
Totally worth the time spent listening to it though.
