For some reason, the sound doesn't work and the game seems to be running slower than intended. Playing on Linux Mint 21.1 through WINE version 8.9-staging.
Even at like 30-50 FPS, it's really hard to dodge.
I don't think I quite got the game. It could partly be due to me underestimating the reach of my sword, perhaps? How do you build bullet deletion meter more quickly? Since most bullets originate from the boss, even deleting the bullets doesn't give much opportunity to do damage.
I would probably be more motivated to give it another chance if it ran well on my machine. Maybe consider a linux export? There seem to be a lot of cool ideas and I do love Shoot the bullet style puzzle attacks, so I'd like to be able to give the game an honest chance.
