All fo a sudden I sat down and decided to implement a looping rooms mechanic into the brand new submachine engine in GMS2.
It was kind of dictated by the nature of that old green-tiled room from submachine 2 sketch. it was wrapping around itself, so I had to add that feature in order to finish that short location.
Once that was done, I also added vertical looping, and arrived at "the loop" being ready for remaster mechanics-wise. :D
