I am trying to make my first game, which I want to make similar to a super smash bros/prince of persia game. I want 10 characters, a major boss, minor enemies. I want the character to be in a castle, and there are 5 doors. Each door has a key inside the room, but the door is a portal to a land where you must fight a boss to get the key. I really want to make this, and yes I know this will be very hard, but I will be willing to spend months/years working on this. My only request from anyone who takes the time to read this is that you help me find which tutorials I will need to use. Thank you.
