Some of the random levels seem to be quite difficult. Particularly where there's a long uphill section I wonder whether it's possible at all (difficult to tell because I can't retry https://github.com/FEDE0D/Planet-Rider/issues/1 ) Meanwhile others are very short so very easy.

Maybe this is all part of the fun of randomised levels, but it makes me think maybe the game should offer a more standard mode, where curated levels get progressively harder. Perhaps that could be presented alongside the "random mode"

In keeping with the space theme, you could play through the tracks on your "home planet" or take a "wormhole random planet"!

When I first played this, it seemed weird that after a completing a level I was only given the option to "Restart".

As a quick fix I'd say maybe the "Restart" button should be renamed as "New level" or "Next track" or something, because it just feels a bit too negative to "restart" after succeeding.

But related this... https://github.com/FEDE0D/Planet-Rider/issues/2

It took me a while to understand that this game generates random levels each time (that is what it does right?). The randomisation is kind of neat, once you understand what it's doing. Maybe it should have a little spinner at the beginning and a message "Generating random level..." to make it clearer
