Lovely game! I really like the game mechanics and the music. 

In the tutorial, it is a bit hard to read what the rocket and the bomb do since you fly by so fast. The rocket is only used in one later level, maybe introduce the controls there. The bomb is never used besides the tutorial, I wish there was a level with that too.

But all in all, a very awesome, challenging and fun game to play!

A lot of fun! Challenging enough that you play levels in order to get a feel for them, but not to a frustrating degree. Other than the music cutting out and not looping, good music!  Overall, good job!

I love it, fun and addictive game play cycle. Good Difficulty scale. Good Use of incorporating different movement tech with each level. my only complaint is music doesn't appear to loop so it just cuts out partway through. Other than that though very well done.
