It would be easier to understand the controls that before you starting playing like a little tutorial level because these controls were very very weird for me at the first time, you should also put a options menu or something for change the controls too.
Anyways it's a good game, you could also try adding more songs and putting different songs because when I hear the same song even if its "randomized" dude is the same song, very repetitive. This needs like a lot of more work, and I thought that a game being made by a like a whole team it was going to be very good, probably I had lots of expectations when I first saw this, but it's like yeah another average game out there. And yeah at the first time the game ran very slow on my computer and I was going to close it but then it like started running normal, so I suggest you to optimize it, I mean the visual quality of this game is very good but you should know how to optimize it, thinking on it like if it had to run in a potato computer dude. Anyways this is my critique and after all is not a bad game, but not a good one too, so yeah keep going on it dude.
