Danmaku - mobile bullet hell game

Hi, I made a mobile-first browser bullet hell game inspired by porting my old mobile game (I created it 17 years ago!). I also improved it by adjusting difficulty for mobile screen and added many features.

It got a decent popularity 17 years ago in Japan market.

The game is still rough, but playable through the end.

I'd love to hear your feedback, thoughts, or anything! Especially improvement ideas.
