The gravity mechanic was well implemented and a lot of fun to play around with, though if you were to change it, I'd remap the switch to one button so no matter when you hit it, it would just flip your gravity from the current state. The platforming was challenging but very rewarding when I finished the two levels. I was really excited to see the boss fight but either the button isn't working, or you didn't have time to add it in- but either way, great entry!
