Cham Blocks comes from Manolo Mazariegos. The purpose is that Cham will eat all the food. However, Cham can only eat food if he is wearing the same colored sock.
I'm surprised at how solid this game is.
1. There is a limit of movement.
2. Blocks can be placed to prevent the bad guys.
3. Bombs cause destruction.
5. Magnets stop your progress.
6. I haven't come to the blast yet
I've solved about 25 levels.
