Rough, but there is some fun to be had, even if I don't know much about surf. The tutorial helped quite a bit, but it was wordy so I kind of tuned it out towards the end. It was fun doing it a second time and back jumping across in <30 seconds. In general, the backward jump seems a bit too crazy fast. I was about to complain that you could move the camera upside down, but it's actually an intended mechanic so that's a kind of neat idea I suppose. The actual levels made me feel lost though so I shortly lost interest. Setting it in an abandoned multiplayer game is cool.
Not my cup of tea, but has potential. Keep working at it.
