Mouse sensitivity feels too high, I felt actively nauseous when i first moved my mouse. The fluorescent green grass and pixellation filter don't help with this I think.
Gameplay wise this was pretty decent, its a competent little 3d metroidvania controller. I like the particles on the attack - feels like it could use some screen shake to sell the juice a little more, but it being at the point where that's the first thing I think of is a really good sign.
Level design was less good. A lot of it feels really haphazard and confusing, and there's lots of weird side platforms that don't lead anywhere. The world also doesn't really have any meaningful side paths or optional content that help give it a metroidvania feeling.
Sound design was pretty solid (except for the boulders sounding like bowling pins? that felt awkward) but I would've liked some music I think.
