plr_trident 72hr Final v1.1

Fixed some visual issues spotted in the screenshots.

Final version for the 72hr Jam 2021. While this is the final version of the map as far as the jam is concerned, I may revisit it at a later date outside of the jam.

There is an easter egg hidden in this map. Can you find it? You'll have to search hard to find the secret to getting it to appear...

* Art pass stuff
* Added new doors from the side corridors to the second track crossing
* Added windows in the stairwells in the side hallways
* Made the doors in the central hallway at ground level the same size
* Reduced round setup time to 15 seconds
