A first, very rough demo video of a couple of key aspects of the game play – phase shifting and replay. You can see the first character, controlled by me, come in and interact with the levels in different ways. The second time I’m controlling the character which comes in later from the right. The character which comes in from the left is replaying the controller inputs from the previous play through. It duplicates the movements (except the phase shifting) so can replay exactly or be forced into different places by the current player controlled phase shifting.

This video was taken by balancing my phone on my laptop while I tried to play the game, hence the quality (and the playing) being awful.
