Pretty violent game here! I still beat every state (not including Alaska and Hawaii, of course). A compelling puzzle game, although some states were noticeably much easier than others (what the heck, Colorado??). In particular the timing of the roots moving and attacking was very satisfying. I especially liked how the roots would move slower when they were winding back and forth, but a long straight root would snap forward almost instantly. 

My one complaint is that the game doesn't seem to allow replaying once you beat it. Before you beat it, you can redo any level you've already done, but once you win you're stuck on the win screen. I even closed the game and reopened it and it stayed stuck on the win screen.
