Big Tower Tiny Square is a platformer game. You take control of a Tiny Square and your mission is to save your friend pineapple, who was taken captive by the Big Square and taken to the top of Big Tower. Jump and dodge your way trough 13 levels of the tower, jumping lava pits, dodging bullets, solving puzzles and wall-jump. When you make it to the top, trying to save pineapple you accidentally open lava flow on top of the tower and kill pineapple. Now you have to go through the whole tower from top to bottom and find the bridge collapse switch so you can end Big Square once and for all.
