Yes, its seeded and procedurally generated, it has set angles it can curve and the obstacles and boost are random. Yes, I agree that the player is a little too small and often in the way, There is a vague thump when you shoot the attack and a gurgling sheep sound when it hits and transforms something, but it seems to get drowned out by the music, you can adjust the volume in the option, by pressing escape.
Thanks for playing :)
