Hello, thanks a lot for trying the game! I'm glad you liked the music, we had a pro on our team for it.
I see what you mean with the head on top, tail on bottom. We actual;y ccame across that option during the development of the character controller. We decided to keep the "flipping" of the player because it was adding to the whimsical and carefree nature of the character and the game. We had thought it would be hard, as I see it has... but on the flip side, I think that is more because of the abrupt difficulty curve. If the game had a tutorial (which we sadly missed out on adding) and a steady growth of difficulty, perhaps it would've been better :)
Again, thanks for the kind words and the feedback, cheers!
