This game is amazing! Currently my favorite Hololive fangame and I hope you keep updating it! I would suggest adding a Boss Rush mode where we have all the items and only fight bosses one after another for an extreme challenge!
Also don't listen to the people saying to change Ayame's fight, it's brilliant, a fight that teaches you to stop mashing buttons and only attack on reaction to the bosses action, every movement is telegraphed so if you pay attention you can dodge all of them, totally my favorite fight in the game!
