Feels good to play! Do the different characters get different obstacle spawning or was that a coincidence? In terms of gameplay I think maybe the player should have less control over their speed, most of the danger came from me just holding 'W' xD
It is completely random, or as random as unity can make it. They are all different size though so might feel different. Wanted to implement a feature that gave you points based on how dangerously you were going down the hill but did not have time.
