So many controls were broken. Had to do my own coding just to fix a couple things but realized it still wasn't an upgrade from 1 and got my money back.

On paper, it seems like just a straight upgrade from Audiosurf 1, but after so many years, there are lots of improvements I would like to have seen. The whole interface is even clunkier than before, the engine is still poorly optimized, and this game bricked the keyboard controls I'd spent 100+ hours getting used to in the first game, just so they could have gamepad support. I had to write a damn script in an external program just to make the previous game's keyboard controls an option for me.

A wildly inconsistent experience, which is to be expected for a game with so many variables. However, I think the developer could have done more to reign in the chaos. The social/competitive/workshop metastuff is a welcome addition.
