I like your game, the music is excellent and the guest rappers, although I do not know them I like their voices, they make the tone of the game more fun in general, although the animations seem somewhat repetitive (something that can be improved) they hit the spot.
What if I did not like it is that there is no difficulty mode that can be chosen, the sounds when you fail are not a problem for me but without a doubt you must put difficulty options and it would also be better to put a mode of separate levels so that If someone wants to choose a song in particular, they can do it and the arcade version to accumulate points I like it, you have to add more characters or rappers but that for sure you can draw for now is all.
