Hey! Great game! :D I'm so mad I didn't take a screenshot, but getting to manage rythm on four different fingers really felt awesome and HARD xDDD Somehow triggered the same part of my brain when I tried to desync my hands on the piano for the first time xD
Awesome overall, with a simple idea that is well executed, I loved it!
Maybe one last thing! I think the rythm game idea on a vinyl would suffice to be elligible on the "loop" theme? And the looping music part with infinite music feels a bit less exciting after 54 rounds, especially when you're back on one track after crying on 4-tracks parts xD
Maybe a game with tracks that end, that you can tryhard again and again would make for a more replayable experience, even if less "loop-y", and overall a more enjoyable game!
Anyway, still was amazing, thank you for making it! :D
