Art and music are lovely. The idea of an eldritch being who's a dad was very charming, and darkly hilarious.
The different modes were cool to play around with, but sometimes it felt like I was just waiting to get an easier combination to beat the level. I wanted to get more out of King Mode and Jetpack Mode, but I died too quickly with them, and then I'd be swapped to something else. I never really got familiar with them.
The randomization of stage hazards was some nice variety, but I'm little less sure about randomizing movement modes. I might've preferred levels designed around one specific movement mode more, so that I could master the quirks of each.
Still, this was great! I'm amazed at what people like you can do in such little time.
