I love the twist on the classic "save the innocent" and having it become "capture the innocent," since it's a really nice twist! I also love the end. No spoilers here, though... (I'm not that person.)
Level 6... Oh boy. There is a part in level 6 where you shoot ice on the sides of platforms to move them, with small challenges in between. But if you freeze the fire demon and it hits the fire on the platform, all animations (excluding the ice bar flashing red if low on energy and the background) stop, making the game unplayable. It is literally impossible to move or do anything... Please fix this, but otherwise, amazing game.
Sometimes the poops will glitch out and allow you to click them multiple times before they diappear. That includes the golden poops. Maybe you will fix this?
