What i do recommend is removing the unnecessary text like "HOLD" or "NO JUMP" and only show the ZO when the song mentions it (like in the original) because it becomes quite repetitive
a black and white level with the xo song isnt like xo but, it he gameplay looks find but the drops are really boring looking and i think you can go more crazy with energy of the chorus compared to the verses instead of keeping 1 type of deco (like the 1st drop, 2nd drop is nicer) also a darker grey background might fit idk
