What the hell you're supposed to do? This game need a tutorial desperately, even if a textdump, but just any explanation of the mechanics. This kind of games work on understanding the mechanics and finding combinations between, which you can't do if you're a blind kitten in a corn maze. From one run I only understood that somehow pp also deals damage to hp and that if hp reaches zero the thing that does it is dead.
Art is absolutely gorgeous and the system has potential, but is it extremely hard to learn mechanics through what you see alone and there's a lot of things you won't understand unless you gain external knowledge. I have no idea how others learned imbalanced strategies and how things work.
