In some platform games, you have to create platforms to be able to move forward. Well... In the skill games you sometimes have to create shapes as well!
Creating shapes games will need your common sense, but also your imagination sometimes. You will have to balance or unbalance constructions, to wake up sleeping boxes and all by creating some shapes.
Don't worry, no need to be a great artist to play the creating shapes games. A bit of savvy will be enough.
