Incredible! Great graphics, great mechanincs, amazing music! Very well done! The only thing is the lack of music volume, being a music game i think it is important to have one and maybe a tutorial level or some instructions mesagges. I took some time to undersstand that the hit was with a full red bar and not the green, at first i thougth green is to go, in this case to hit jeje so maybe that migth be a good adition some instructions.
Great game!
