This is a solid proof of concept, it's biggest problem is the lack of knowing who is who. When I got to the "coder required" doors it was like... okay cool but they all look the same. It should be a "sacrifice" sort of deal.
The first "manager" attacking you immediately while not being able to quickly open a door was a pain because he was off screen. Not that it was hard, he was off screen.
I didn't feel like playing the whole game because up until I needed to use a mouse, I didn't expect to use a mouse and honestly do not want to.
