The whole jumping thing feels really weird, and the fact there is no sfx, or visuals to indicate that we bump into a wall doesn't help. Also don't know how I feel about the upgrades being random. In certains runs you can have multiples, or in another one 0.
But I very much like the "die and retry" aspect as the road blocks are not random. I guess the camera being this close also helps that feeling of having to know what's next. (especially if you take too much speed upgrade...).
