Very nice, really polished and a great interface. Fun game idea. The text in the help screen/intro could use some polish.
"Each player starts with an equal amount of circles representing their moves."
"Each circle gives the player a point when it reaches their colored zone. If 2 congruent circles are landed, the player gets a bonus point"
"Reach the colored space and flick away towards the opponents circles to defeat the opponent."
"Player captures the opponent's circle if it lands in their starting area. The circle becomes smaller."
"Lock button freezes circles in place for one round. It can only be used once per game."
Feel free to tweak those for brevity if you need to.
Also, on the game pause screen, the text doesn't change colors when you tap it like it does on the main menu. This kind of has a jarring effect because you can't tell if it detected your touch or not.
