Here it is.
The longest currently working map in Trackmania 2020 - [PF] The Spacetime Continuum.
This map is 10 minutes, and 22 seconds long, and is built very similarly to my other PF maps, with a high concentration of tricks (except for a few relaxing areas).
It took 3 weeks, and over 50 hours to build, and was by far and away the most difficult map I have built yet. It is so compact compared to other long PF maps, which made it tricky to find paths through at times, and the longer it got, the more difficult it became.
The map contains so many different ideas, some high-speed sections, some very low-speed sections, some oddly satisfying sections, some fragile and slow-mo, lots of reactors, and many, many flips.
The scenery is minimal because the track itself provides ample scenery for most of the map.
There is a longer PF map on TMX called Xenon by SlurpyCollin13 at 19 minutes, but it doesn't flow as well as this one, and no longer works, hence the title. I like to think this map is very much built like a short PF map but extended over a much longer period.
It turned out way better than I ever expected, and I hope everyone who watches or plays the map enjoys it!
