I have an idea that I have been thinking on for a few weeks.
I think it would be a great idea to add custom map making, now this would also be a whole different game mode chosen by the player themselves.
How I think custom map making would work is allowing the player to go to there own sandbox. They will have a menu of (walls, floors, furniture, and task objects). Players would be able to make there own spaceship and even put tasks on the ship. Although I do think these custom maps should only be private matchmaking. Just because we wouldn't want people making toxic maps for the public.
That's it for my idea. Thanks!
