Wow, there's a lot of good about this game!
The music and VFX stand out to me as really good, making the game feel much more polished.
The title art too is very eye-catching and well designed.
The enemy designs and pixel art are all very cute.
The world design is also very cool (nice touch with the parallax). I think it could use some lighting to create a greater feeling of discovery/intrigue that would work well with the music track in the beginning. It'd also be cool to see some secrets and hidden things but I know I know I'm asking too much for a game jam hahaha.
Also maybe just me, but it wasn't obvious to me that I would be able to freeze the tops of the waterfalls (which I assumed to be background assets).
The controls are alright, certainly of good quality for a game jam, but could use a few touchups:
-It feels a little difficult to control where the potions are aimed, especially when your target is something like a small bat flying around.
-Personally, the movement could do with being a little snappier, it currently feels a little bit too slippery for my taste.
-The ordering of the buttons feels a bit weird, and the change potions button wasn't taught in game I think? Using zxc plus arrow keys as my controls, c would feel natural for jump... I guess I'm being quite picky with this point lol.
