Past 72hr Jam Entry tinyrock4 (Jam version) a2a

* Enabled trigger brushes. doy.

a2 - 25/05/2022
* Turned some cliffs into buildings to add more team colours (and general colour variety)
* Added some health and ammo packs
* Closed off a couple dodgy sightlines
* Tidied up some geometry that players tended to get stuck on
* Added some "danger" signs
* Updated clipping
* Updated lighting

Note: There exists a bug where the map doesn't detect all players on one team are dead if a player joins mid-game. I'll fix this eventually, but not today.

* Only dead players should respawn on round start now
* Changed map prefix to "aplr" since the servers are funny about maps with the "arena" prefix
