I really like this game a lot, but there's just this one problem-- the fights go on too long. Once you've mastered the mechanic of a given boss fight, you're just doing the same thing over and over again for too long a lot of the time. Also, a lot of the boss health meters stay full-looking for a large portion of the fight, making it kind of confusing as to whether you're ever going to win or not. Jumps are maybe a little floaty but overall the basic fight mechanic is sound. Fights might take too long but they are satisfyingly tense.
The artwork is super-cute and the dialog's weird, snarky vibe is a delight. I would love to see this built out and deepened!
