When you were young, you could jump very high and walk very fast. Now you're an old man and you don't manage to do all these things that well anymore. Or is there a way to turn back time? Go in search of the alarm clock: it might have the answer to your question! Take the magical sand: it makes you feel younger and you can jump higher. Avoid all the obstacles and undergo rejuvenation: the further you get, the younger you get!
Use WASD or the arrow keys to move around. Press the spacebar to jump.
