This game was pretty challenging! Though, I'm not experienced with or very good at bullet-hell games in general.
I was able to beat it after several tries!
It's be nice to have an intro page, story, or something before getting tossed right in. Without that, there's not a lot that screams "Magical Girl" currently.
I'm glad the controls were very simple and intuitive. The graphics and audio were all solid. I actually didn't have much trouble until the boss, who was quite hard! (For me anyway)
I didn't initially understand the enemies were dropping power ups on my first playthrough, but I caught on by my second try. One possible bug I noticed was that my "dodge" count didn't reset after a game over.
There's plenty of potential here! I'd love to see this fleshed out with some story, additional stages, etc. As it stands, it's a fun demo that kept me on my toes! Nice work!
