A very charming experience! The aesthetics are really nice all around. I like the low rez pixel art, and the audio experience compliments it nicely. The overall game concept worked well and was fun.
I think others have mentioned it, but the walk speed feels slow. I could see the walk being the current run, and the run being even faster.
I guess my only other complaint would be that it didn't feel very magical-girl. Maybe a little extra story could make that aspect a little more prominent? But otherwise, this a very good entry to the jam. Great work!
