Nice, congrats on finishing a game!!
my high score is 47.
I feel like giving the player a little more grace would make it more fun though just because if you touch ANYTHING you die instantly, and sometimes you are boxed in by trains so there's really no avoiding that. Like even if you didn't implement lives, if you made the collision shapes a tiny bit smaller so that clipping the very corner of trains wouldn't kill you, that would be more fun imo. But maybe I'm just not good lol.
