I don't think he will. this is his exact post(plz don't sue me.)
"1. It's a complicated system to implement a colored pet, none the less another animation for a pet.
2. Wdym it's in the game just click the map icon 3 times.
3. Skolus HQ is my fanmade (and favorite) map that's been in the game since the beginning.
4. Skins have to match the player animation which is complicated and not a priority.
5.Crewmate is a useless addition that would not satisfy everyone's crewmate obsession because of A.I imposters not being great at hiding bodies and killing in a good place. Tasks are also a really complicated story + assets and functionality, I would have to add a layer for each and every task.
6. Polus's main point in the original game is the doors and vitals. Which means I would have to create my own pathfinding system and crewmate death detection. This would improve the game and might come in the future."
