So, I had a lot of problems with ideas, because the entire map is made improvised.Originally I planned demons to the map, I tried, but I had to figure out, they don't fit to the map:/
Also I've added an elevator scene and expanded the Cellar, but I don't plan to expand any other map.
I've learned how to use Practical Systems and sounds.
Some puzzles "don't need inventory" so you have to grab something and swing it to an entity.
For example: you have to pick up a rock and throw it to a wall so the wall break.This one isn't in the map, but it was good for and example.:)
