How about cutting down on the Game Ark introduction time a bit? Feels like it takes at least 8 seconds, a bit too long for just a quick show of logo. As for the game itself, it's great! I love the combination of TD and puzzle, it's just like the classic click-matching-colors games, but with a completely new perspective added to it. Also a pretty entertaining interface, like the teeth you knock out on the main menu. Great game!
