Very cool game, loved the colour palette you chose and the lighting effects, and the puzzles were very satisfying. It would have been nice if the character was animation. I thought a cool idea if you wanted to develop it further could be having different trains with different puzzle types - e.g. a red themed train with a tetris puzzle or something.

Really nice visuals and you implemented the pipes puzzle mechanic well. I don't think there's a need for the Quit button in the main menu if it's being played in the browser.

The color palette and drawing are really good, the music is a bit hardcore but fits the theme. 

I really liked graphics of this game!

Exciting! Matches the theme extremely well. Great atmosphere.

Remarks:

• Took me a while to figure out the controls (no help text)
• Ladders distracted me..maybe I can go down?
• can go back, but clicking a puzzle shows its original (unsolved) state
• Me noob, Me want checkpoints

Loved the look of the scenery, and the mini game was fun.

i win!

Music and puzzles are too good.
