Dank Room Escape
You are trapped in a place where the humidity is overwellming, to the point that you can see traces of humidity in all of the rooms. The air is damp and the smell is strange in here, so you need to get out of there as quickly as possible. Trying to open the door, you find that it is locked and that you absolutely need a key so you can escape and finally breathe fresh air outside. The only means available to achieve this is to find objects and clues that will help you solve the different puzzles in this place. The faster you find the key, the better it is for your own health.
