Plug Me Portals Walkthrough Cool Math Games
Each of the 12 levels has a charging scale that decreases very quickly. In these few seconds you need to run to the green platform and jump onto it. If the scale decreases to zero, you will need to start the level over. There are sometimes blocks on the scale that fall when the platform below them disappears. The game also has teleports. At the last level, you need to destroy the boss, on which you need to jump from above three times. In addition, each of the levels has an optional battery that can be collected. The game is taken from the site Cool Math Games.
