Cool idea! Maybe needs some balancing in terms of speed - probably a more meditative style would do, or a choice of speed for slow-clickers :)
Sooo cool! Tough at first but once you get the vibe and rythm it gets so fun. Speaking of the rythm, some bg music might fit well here to keep you going (since you can't stop anyway :)
Great idea of these mini-loops, makes it hardcore but rewarding! :)
