I really like the feel of the motion in this game barring two things.
Firstly, please let me double jump without having to be actively falling, or state somewhere in a movement tutorial that you have to be falling to double jump. Until I figured this out, I thought that the double jump was just unreliable.
EDIT: Having replayed this a bit and getting that it works like a glide, I actually like this mechanic a lot. Only thing I'd say you need to change for sure is the conveyance of how this works. If I were making this myself, I'd make it faster to use after your first jump and then subsequent flaps can only happen while moving downward. That would give the double jump feel people are looking for while keeping the timing mechanic to keep yourself adrift for longer gap. (Here's hoping this game has fun navigational puzzles~)
Second, the pogo is a little weird to use, since you still have to be holding down for it to activate, but you get the same amount of arial pause even if you let go of the button. If I could get the pogo jump as long as I jump during the pause it would likely feel better.
As for feedback on a non-gameplay side, I really would appreciate being able to change my key bindings. Attack with the rightfaced button feels really weird and I keep accidentally casting magic instead.
Other than those gripes, bravo! This has been the best vore themed platformer I've played yet and it feels genuinely good to play and move around~
