Best graphics I've seen on a bubble breaking game. Also enjoy how the broken off bubbles have a chance of flying back up to make it a bit more interesting. The LMB "follow" feature I've used quite a few times and love the implementation of it in this type of game. Great job!
very fun. i suggest that some weapons (automatic weapons) come with more ammo though, as they run out much quicker than others like the shotgun or crossbow
