Great job, love the cute artstyle. Overall a pretty solid platformer, if a bit rage-y. The gravity mechanic reminded me of VVVVVV. Good amount of polish for a gamejam game!
I did feel like theme interation wise, the bugs kinda didn't feel buggy enough. like, my initial expectation was that i'll be able to walk through all walls or that gravity would be off and I would float and would have to use the inertia to navigate. Same with the stability, eventually I just get zapped, but nothing particularly buggy happened. The actual mechanics are not bad at all, Just didn't necessarily feel buggy or errory.
Also, the gravity flipping mechanic felt a little bit unintuitive, I feel like the way the inertia buildup worked just didn't really jam with my brain (specifically in that boss escape level where you have to float in the middle) like, the first flip it kinda accelerates suddenly, and then it is sort of smooth/maybe some inertia gets carried over, idk. hard to say, probably it's just skill issue hehe.
but to bring the example of VVVVVV, IIRC that game didn't carry any inertia over to the gravity flip, so while it was challenging it felt very consistent. Might be worth experimenting with.
Nitpicks aside though, great job :)
