Really nice presentation, I like that, even though the exact blocks I roll are random, I have a lot of control over the types of blocks they are! It really helps offset the randomness, and made clearing waves feel a lot more strategic. The only issue I ran into was that, by having the slingshot so close to the edge of the screen, I found myself occasionally dragging my mouse outside the game window and losing control. Fairly minor issue though, and overall I really enjoyed the game!
