Damn, I wanted to keep playing. Nice demo (I played as Rosemary) and appreciate the multiple difficulties because I'm not good with bullet hell games. Please, consider adding controller support for the next version.
Well done creating the atmosphere: level transition and music fit very well. I also enjoyed the bosses and mechanics. That menu wheel at the start was a pretty nice touch too.
Only thing I struggled to understand were the bird's (can't remember its name) feathers. Their shape could be a little polished and the fact that the bird is dark but feathers are yellow-ish don't make me associate them as a group.
Nice game, team.
