also the reason i found this was because i looked at the assets like ys do and found pico assets that went unused like when you miss a note yeah both bf and pico have them
also it would make use of the custom characters folder (like the more you make the more you have on the character select screen) and make them all selectable from a character select screen and after you can change the settings of the battle aka multiplayer and then play the battle
no as my brother and me are used to splitting up our hands and i use as and ^> or 8 6 on numpad numlock off so wasdtfgh and pl;' up right down left really works for me (ps i beat the game on hard mode)
Maybe a 1v1 mode for me to 1v1 my brother (wasd, tfgh for player 1, pl;', arrow keys for player 2) also both players can select their difficulty and the higher the difficulty the harder you score on your opponent
