unfortunately, this game is not working at the moment, but you can try Keyboard Climber or Typing Rocket which are almost the same game or try other Typing Games
Play in Fullscreen Mode
In the Jump Key game, you need to help the ball reach at the top by typing letters correctly. Please note that when you see a Small letter, type small letter, and when you see a capital letter, type capital letter. It’s not a jumping and moving game, you must type the correct letter to jump to the letter.
