I've only finished one Touhou danmaku game, so I'm not exactly a pro, but I enjoyed the few tries I attempted at yours! The slowdown mechanic is interesting and works well with the patterns you devised, although I kind of miss bombs.
Thank you for trying my game! I wanted to explore more with bombs, but I also wanted to let the patterns be the focus for this jam.
Then you did a great job! I enjoyed the patterns.
