this game is awesome, i only have a few sugggestions! firstly, an option to have the hitsounds' volume be consistent would be fantastic, as it sometimes not playing as loudly can be really distracting. also, losing 200 points whenever you miss feels INCREDIBLY punishing, especially when the actual game doesn't lose you any points at all. a different scoring mode (probably'd be best if we can switch between either modes in this scenario!) would be really nice in that case, being more similar to how it's done in deltarune, especially with how i think it's not humanly possible to perfect any of the songs with the current scoring system, with how precise getting a +100 is? (i think the way deltarune's scoring system works is you can either get 50 or 100 points for notes, and hold notes give score over time and round to the nearest 10 if you let go early)
hope these ideas help a little, and i'm looking forward to the next updates !
