I LOVED IT! I'm surprised this isn't getting more attention, I thought it was one of the best.
The character and models are so clean, and flying around is a ton of fun. The world needs more 3d platformers and more 3d pixel art imo, such an awesome game format and hard to pull off, so nice work!
I didn't really understand why I'd ever want to turn gravity up, seems like moon jumping was just a huge advantage for everything and was all around more fun haha.
There's a lot of polish here, and everything works together and you made it yourself!? Just wow. Fantastic job!
