Really neat game! I think the mouse only controls work great and the theming led to all of the objects working cohesively, although I do think the objects seemed kind of arbitrary in relation to the game, although maybe the buffs system would make that make more sense. I really like the skull's animations and the animations when you open a pack, and I think the audio was nice. The stats weren't really explained in the tutorial which was pretty confusing, it takes a lot of messing around until you get any grasp on them. Overall though, nicely done!
