Boksy Boy leads a simple life, bouncing around and what not. Boksy Boy is quite square but not square in mood. On the contrary, he is enthusiastic and optimistic that he can help unlock all of the other Boksy characters without crashing into the floating beams... at least not too often.
It may look simple but looks can be deceiving. Timing is everything. When it seems like you should tap boksy boy upwards, it may be best to let him fall down a bit first! Try your best not to throw you iPhone in frustration. They are quite expensive.
