I see it's been said already, but the game did get way harder without the guiding circle. I kinda like the difficulty, but it seems less intentional and I admit I couldn't get much further without it.
Otherwise, super cool stuff! It's a neat take on the Loop theme, the art (especially the bat) is cute and stylish, the music is good and I always like having different themes for different levels in a short game. Even with the circle thing, moving the bat feels responsive and quick. Nice job overall.
