Runs smooth on a Nexus 10.
I like the simple gameplay. Fun for any age.
Agree that extra lives would undermine the idea= one life to see how many points and coins you can get makes it more fun, IMO.
The dragging coins to the chest makes it more difficult and competitive. I like how you aren't just awarded the coins, there is risk in getting them.
The ability to disable ads by spending time in the game is a great idea.
Good job.
