Fun game! I like the simple gameplay loop of kill it to feed your pet before it dies of hunger. The attack felt a bit clunky to me, it would queue up my click when I didn't have enough mana and make me instantly shoot once I gained enough mana to shoot. Also the recharge was a bit slow for my personal taste, I kept wanting to be able to shoot more often and waiting for the long recharge felt like a punishment for shooting. Also the camera shake got to be a bit much after I hit 10-12, maybe locking it to not go over a certain value would help.
It was very satisfying to grow my pet and watch him get huge. Cute little game! :)
