This is incredible, especially given the short time period! I really liked the visual style it worked really well. I did feel the player moved a little slow, but it wasn't a big issue
My biggest issue was actually the sound, I found the jump sound and the dialogue sound sO annoying I had to mute the game. I tried lasting out because I really liked the background music, but it was just grating around in my head too much! The signs were also slow to scroll by, so a skip dialogue or fast forward button wouldve been VERY appreciated!
I think it says a lot that my only real grievances were just minor annoyances, so good job :)
I also would've had a slower introductory level where you taught the player the basic platforming (since you have a ton of cool platforming abilities) before you introduced the magic system!
