BlockDodger (demo)

My first game I've made, hoping to release onto ios at some point and would love some feedback on level difficulty as well as anything else you can think of. Also I'm planning on making this for ios and hopefully android so the actual difficulty won't be the same. Thank you.

Buttons - press space to change rotation straight forward can pass through green and 45 degree angle can pass purple. Q, W, E and R keys to move. More instructions in game.
