As a puzzle game, I appreciate the effort you put into making the puzzles, but there was a bit of a difficulty jump near the end. You might also want to include download instructions by telling people to go to Time Jumper/dist/main in order to open the game, since I had a little trouble in trying to figure out how to play your game. It's also lacking audio feedback, which is important for people to feel responsive controls, and you could've used "press key to do thing" instead of buttons in the menu. This has a lot of potential, and good luck on your next game!
