2gether is a small platformer game that is trying to describe diferent types of power:

power = strength

power = friendship

power = solitude

power = speed

The mentioned types of power are illustrating by  solving small puzzles: you will need to push some boxes for strength; to receive a key and start an elevator for friendship;

to get out of  water for solitude and speed. 

As the game will advance, the difficulty of the game will increase. In the end the important idea is to follow your goals because you will find the power to achieve everything.
