I'm... so sorry... I really tried to make sense of it, but... I just can't. It feels like a mess to me. A lot of aspects, such as pathfinding and walk speed, are just not it for me...
Even I got stumped on the first level... I wasn't sure what I was supposed to do. I drop him on the right, nothing happens. I drop him on the left, and the box drops on him and I have one less guy. I tried thinking, "shake him out?" but to no avail...
