At first I was confused how to get to the train car up on higher platforms, but then I realized the train could JUMP! Pretty amazing lol. Then the train could also double jump and dash! I got pretty far into the game, a few of the jumps were really tight needing pretty precise jump/double jump/dash combos, but overall really nice layout. I did eventually get stuck on a later level where there is a one way grass barrier at the upper right. Not sure what combo of jump/dash I needed to solve that one.
