[Android] Grow Defense

Hello all, I've been working on Grow Defense for a little while now and would love some feedback.

Description:
Incremental Defense game with Idle and Clicker components. Basically Upgrade your defenses and unlock various weapon to defeat waves of mobs and bosses. There is a leaderboard to go up against friends as well.
