It's great to hear that you still play the game! I don't think I currently have time to go back to that game, but I'm working on an upcoming fps game that will have gamemodes similar to Cool Forts Prevail. I sadly don't have too much time to work on games since its only a hobby, but I will surely keep your ideas in mind if i could find the time :)
Can you make splitscreen then for the new game?
Already done :)
