I'm glad you uploaded an executable, the index failed to load for me. It was a bit awkward that it was an install instead of a folder, but I'll live with it.
This is very cool! Some of the menu interactions were awkward, but the one-button control worked very well. I'm fond of ball-rolling platformers, and this was a good execution of that.
I love the art! It's saturated, but easy-looking. The older music fit very well with it.
The camera was a bit claustrophobic. I think it could be zoomed out just a tad.
Great work!
