Guide this little man through all the levels and brave the dangers and obstacles that he'll encounter! You'll have to make your brain work hard from time to time, because at the first glance certain obstacles seem impregnable. He passes by various checkpoints, where he has to pull levers to go on to the next level.
Use WASD or the arrow keys to move and the spacebar to jump. If you want to make a sliding, you press D+S or the right+down arrows. If you want to walk up walls, you press either W, then A, and then again W, or the up arrow, then the left arrow and then again the up arrow. Press P to pause the game.
