Operation: Rescue Klaus - A 6th Level Puzzle-Filled Adventure for D&D 5e

Hello everyone! I've been DMing for quite a while, and would like to share an adventure I made with you.

This is a Christmas-themed adventure, in which a group of elves needs to rescue their employer, Mister Klaus, as he has been kidnapped. They need to solve increasingly difficult puzzles focused on deciphering secret phrases, based on context cues and a set of fun rules.

The adventure consists of a PDF file, as well as a couple of assets (images of maps, puzzles, items, character sheets and photoshop templates), all of which can be found at this link: https://drive.google.com/drive/folders/1dxQEk-AgQXg8-3HH49u_OcomTVP_w5W6

I would love for other DMs to give this adventure a chance, and I'm definitely looking forward for any and all feedback I can get. Please don't hesitate to comment or message me.

Have a wonderful day!
