I really love the aesthetic of this game! High quality pixel art, a nice color palette, and a good atmosphere overall! Reminds me a little of the Momodora series, which is a person fav of mine. I also liked the transformation moment when you get the spear!
The idea of a magical girl fighting a bunch of cuddly rabbits (and muscle rabbit men) is inherently amusing, and I enjoyed that as well. The music and SFX all fit nicely.
The platforming gameplay has a lot of good ideas. The ledge grab is a good mechanic, and a spear is a great weapon choice. However, I found the overall physics and controls a little clunky. Jumping and maneuvering through some of the harder sections felt tedious more than fun, and I often found myself getting hit by enemies as I floundered around. One other thing I hugely missed was some sort of aerial attack. Being locked into the flailing falling animation, while cute looking, became frustrating during combat. I got more adept at the controls as the game went on, but it always felt a little off.
Despite the challenge, I did manage to beat the game!
Overall, I do think this is great work! With just a bit of work to streamline the physics and control, I think this will be a top notch metroidvania!
