Love the art style of the game!
Cute story as well.
Also, I found it pretty unique that the MC made her own magical outfit. (At least the few Magical Girl shows I've seen, it's always an outfit that is already made for them or a reflection of their heart/ personality or something lol)
In addition, I'm surprised that Ren'Py was able to add a mini-game within the Visual Novel format.
It'd be neat to look into checking out Ren'Py's other capabilities.
Great work on this game!
