I think this is my favourite ProcJam entry of yours yet: the vibes are immaculate, the gameplay feels really good and is a bit addictive (the seamless respawn in particular, with the music track restarting, feels great), and the level generations makes every flow together without a hitch. My only issue would be that ravine on your last screenshot that killed most of my best runs (I managed a highscore of 10280 in case someone is keeping track :-)).
I remember you did car generation once; how hard would it be to get that into this game to have a different car for each run?
