The idea is good but the puzzles needs to better the rules, right now it is just moving back and forth most of the time. At some point Idk, I was moving without thinking much and window popped up saying no valid path forward, and game started from lvl1. You should make it so that it starts from the same level, otherwise player will leave the game.
Think about these feedbacks and improve your skills, and keep making more awesome games in future. Good Luck!
