Some of the reviews are very harsh, this is far from a 0 or 1 star game, the bare bones are there but the game could do with a wider area to surf and the ability to move from left to right as well as maybe crouching to mix up the options and keep it fresh for longer. Also landing on top of certain obstacles like the cars shouldn't be a wipeout and landing on a crow from above should splat 'em Mario style.
I have no problem with random obstacles however they should be in waves with clearly defined methods of defeating them or going around.
I didn't get very far (so my apologies if this is already the case) but changing environments as you surf would provide visual rewards to the player without any real gameplay changes. As well as different hazards depending on the environment. idk
