Made it to the train on my first go with the ten lives thing. Not sure if that's good yet, but was a fun game nonetheless and I'm going to complete it now on easy. Hard seems like a challenge better done after completion once. I love platformer games and this is quite good. I would say that a little bit of definition (i.e. colour difference) could be useful between background and what you're meant to stand on, though I like the eerie, sort of empty design. Nice!
If you ever need music in the future, I make music and I'm sure I could make something for a game like this. Would love to collaborate.
Cheers, and good game!
