I liked it !
I feel like the difficulty might be a bit unforgiving once you get far enough though, the rail-hopping animation end-lag ends up being the run ender for most of my tries, and in the end it just feels bad to die to an un-reactable obstacle !
(rails eventually appear way faster than you can actually switch lanes, which ends up stopping you around 150+ velocity)
(would have also needed a way to hop to the opposing end of the track since you sometimes end up reaching a dead end with no rails to your side.
The arrow showing where safe rails are is a good idea but it ends up being wrong occasionally and straight up sends you to a dead end with no hope of surviving)
Still really enjoyed the art/sound direction though, gave me a really good first impression when first starting the game ^^
Nice game ! Good work <3
