I have a tutorial for a game in unity that is already made it is in a seperate scene and has its own option on the main menu. so how do I make it so that once the player hits the end of the tutorial it brings the player to the main level scene and marks the tutorial done as a quest, and how would I make a goal that once they hit the final room it completes the tutorial? And then if the player choses to not do the tutorial and go straight to the main level how do I make it so that the tutorial quest doesnt appear or automatically marks as complete and then how do I make other quests like kill an enemy and make it complete when the player kills the enemy. the game code is in C#
