Nice!! You should really keep playing with this concept because it's really cool that the loop is always playing. I think some other comments have already mentioned the separation between trying to make cool sounds and the incentive to just put the best blocks up there. But if you gave me just four days to try to solve that dilemma I couldn't do it lol. This is really great and I hope it can expand to include combos like "make a backbeat" or "four on the floor bonus"!
