TL;DR - disable mod in modlist, safer and easier

For now the only option I'd suggest to "play regular duck game" is to disable mod in modlist options. However, you could just invite friends, configure lobby normally and then just hold F1 + start to start regular Duck Game session. I will add feature to switch between modded lobby and normal one later tho, but it still would and is requiring all players to have mod installed and due to the way I've added stuff to the game, random boxes might drop items that has no use for regular gameplay

I would really like a way to choose between playing this game mode and the regular duck game. Unless there is a way to do that and I'm just stupid...
