This was a really great concept... I really liked the idea of having to watch over two character concurrently and the method of switching between them, having to reverse your thinking control-wise was really challenging. The fish eye view was a really great touch and gave the whole thing a sort of sleezy, security camera vibe.
One improvement I would have made is to give the character more of a health bar and give some kind of audio feedback when getting hit. It felt like you died too easily and I wasn't too sure whether I'd hit the enemy too many times or simply got hit once.
Some really great stuff there though!
