I noticed it said unfinished entry so I will take that into account when giving my rating.
I was disappointed there was no sound, enemies didn't do damage, and I was lost as soon as the game started. Now that's probably because the game is unfinished.
I will say that the art was amazing. Really good train and enemies. The character looked super cool. Good walking and kicking animation! The inputs felt a little laggy at times. When you hit spacebar the character seemed to wait then jump which didn't feel good. I would rather have a more snappy response.
While I was playing I got stuck in the train car and couldn't get out. Would have loved a restart button or just kill the player if he falls in!
It looks like a really cool concept and game! Hopefully you keep working on it!!
