I got some fake news! Pelican will be adding game modes in the not-too-far future! at least, that's why I hypothesize.
When I was running around (forgot the map name 😑), I found this brown blob hovering over the center of the map, positioned over the boat. I think this is a control the point game mode in early development. I also saw this blob in Temples and Jungle! (Which I sadly did not take pictures of). Here, take a look:
edit: They are just arrow blob glitches that have existed for ages, nothing special.
