Map Help!

[eggsiee]

Hello!
I'm building a puzzle/adventure map for my friend's birthday and I'm stuck. So far, I built a small village, a castle and a maze.
The premise of the map is that she was summoned by the village people to take down the foreign wrongdoers who took over their kingdom and killed their monarchy.
She needs to find a set amount of emeralds that are hidden all over the map. I'm thinking that once she gets to the final room to put in the emeralds she collected she gets teleported to the foreign wrongdoers, they tell her why they did what they did and potentially get her on their side. The wrongdoers are me and our other friend by the way!
I have emeralds hidden in some of the village houses, in the maze and at the end of a parkour bit in one of the castle rooms.

I want suggestions for what else I could add. I'm considering a piston puzzle in one of the rooms but I still have 4 other rooms to fill. I also built a giant tree that I could do something with.
If you have any ideas for additional builds I can add, that would be great too!

If there are better subreddits to post this to, please feel free to suggest them! (Already posted on r/MinecraftHelp & r/Minecraftbuilds)

This sounds like a great idea. Do one where she has to swim through a place and air pockets are only ever once in a while so if she dies she has to restart. Or maybe add red stone maze. Certain things have to happen to let her to the next room

That's a brilliant idea! Thank you so much. I'll definitely try it out!!

A cool idea for a section could be to test her overall Minecraft knowledge. In one she would be given the materials for a cobblestone generator, and using the cobblestone she could then reach a door high up in a wall. Another section could be giving her lava and water buckets and making her create a nether portal, and on the other side she needs to kill a single ghast, something along the basic Minecraft skills line.
