I really liked the remake idea, but it's a shame the project was abandoned. It was looking great and was very well made!
I wasn't completely sure about the final door. Since there's no texture behind the vent, I couldn't tell if I was doing it the intended way. It seems like it was designed for co-op, with players entering from above.
If the project were ever resumed, I'd suggest adding a box or chair to make the climb more obvious, as well as adding a texture behind the grate. But since the map was abandoned, I guess that's unlikely.
