This one is easy. For a moment you scan the other options, and then realize that this is the only correct option. The others will only get you
into trouble, if not transformed.
So you open the door. As you open it, your eyes widen, and you suddenly realize you're... outside?
"Wait, what the hell?" you ask. "No way. It can't have been that easy."
"IT'S NOT, CHAMPION."
Nice job jinxing yourself. You're on a path. There are various plants bordering the path, and as you continue you come to the conclusion that,
no, you're not out of the proverbial forest yet. Or an actual forest, as you find yourself in.
You follow the path, as any deviation could result in you losing your original form. However, soon it begins to turn dark.
Dark? You've been outside for quite a while now. And luckily, you come across an intersection right on time. One path leads to a cottage,
another to a dark inn, a third to a (sigh, you mutter under your breath) carnival, and fourth to a huge tree.
"Seriously?" You say out loud to no one in particular, except maybe the narrator, "who would ever enter that carnival? There are like at least
three in this story branch alone in the beginning two pages, and most of the options involve a transformation. You'd have to be a complete
loser to enter the carnival."
Remember, the goal is to make it out unchanged.
