i like the idea, but i'm not able to get very far. its really confusing figuring out what makes a loop (up forwards back down?? forwards down down up back down forwards??????????) and sometimes it starts me off with only ups. i would have recommended making the game easier to restart (had to refresh the page each time) to compensate for the lack of balance, but overall it was a really good concept. i could see myself spending hours on this game if it was a little easier to understand and had a balance system. good job!!
