I kinda gave up on level 7. It's very difficult to gauge when exactly the coin will distract them. When I finally got past them and did the computer there's not really any room to distract again before the other guy comes back. And given the movement isn't grid-locked it's also very easy to just just stuck when going through a door and impossible to just turn around without moving.
It's otherwise a great game, and very well done for doing everything yourself (I think I only ever did that once, I rarely do music). Good job!
