Resizer Walkthrough Cool Math Games
The main character can change his size by going through special transformation squares. The small shape allows you to pass through narrow passages, the large one does not obey the actions of the shooter and breaks down the springboards. Of course the size of the blocks will affect the jump height and the ability to move the wooden blocks. There are also bombs in the game that can destroy part of the level. The game is taken from the site Cool Math Games.
