You're inside this cabin with only one door. Have you tried opening the door? Have you tried interacting with the diorama in the middle of the table? Can you see something preventing you from opening the cabin? If you click into the diorama twice, is there any areas on the diorama you can click on?

You need to interact with the diorama, zoom into by interacting again, and then rotate your view until you can see the outside of the door. From here, you should be able to click on the lock of the door and then open the door.

You're now outside into the forest! Is there anything you can see immediately after exiting the cabin? What's inside your next diorama? What is outside your diorama? What would you need to cross the river?

On the diorama to the front left of the cabin, you can find a bridge piece outside the edges of the diorama. Zoom in, and click on the bridge. After, click on the middle part of the river to connect it. Now, check the river.

After some exploring over the river, you might have found a waterfall with some candles on the other side. However, when you enter the nearby diorama, there isn't a convenient bridge to cross this time! Is there a way to get a bridge into this diorama? You already have a bridge, I wonder if there is a way to move it to where you want.

While crossing over the river, there is another identical diorama with the bridge piece on it. If you pick up the bridge piece and exit the puzzle without picking it up, you can take it with you. After, you can bring it to the waterfall diorama and put it on to cross.

Past the candles, you find a weird coffin with a diorama inside. When you enter it, what do you have to work with? What could you possibly do with the matches? If you've figured it out, you might notice you're carrying something in your hands now, how weird. And you can't put it down! What could you put it on, or into? Maybe the diorama itself was a hint where to go?

After entering the coffin, you need to use the match to strike the fire on the mini campfire. After lighting the campfire, you automatically pick up the diorama. You need to bring the diorama back to the real world campfire and burn it.
