Well done. Very good on the graphics too. Overall very impressed. Did you make this yourself soley?
Now my constructive criticism. I chose not to login using google play. Every time I die it re-asks me to sign in. Fix this as it was very annoying.
Also, I would suggest adding a tutorial to change shapes before you land. I got the swipe up and right real easy, but if I didn't watch the video I wouldn't know (trust me, people are dumb and just want to play. You have to hold their hand going to the bathroom).
What did you use for making the shapes? I really like the trailing glow effect.
