10/10 for adding a menu and sound, I would rate your game higher than a good game with no UI. as for the game it was very simple and I enjoyed the challenge. I think the mechanic is quite interesting and I would have loved to see the game lean more into the puzzle genre instead of making it a basic platformer. the graphics where cute but you could have made a separate sprite for the wide arrow block so it doesn't look out of place when its stretched like that.
I'm not Shure how the game fits the theme but that's not a train smash.
overall a good lil game and well done for finishing!
