Progression in the game

Part of creating the narrative

Level Design

Whiteboxed the layout and level 

Created the finished level design

Planned and placed gameplay geometry


Sneak & Hide

Stealth is a main part of the game.

This element was developed in sneak and hide.

We wanted the player to have that creepy feeling of peeking at the monster, which goes well with the unease pillar. You can also see when it is safe to exit.

Exploration and clues

For the player to explore and progress we made drawers openable and clues for the player on how to progress

The chase

The AI is the main challenge in the game and what gives the game it's dynamics.

Feedback on what the AI was doing was also hugely important. We added special music and a sound when it heard the player and a screech and screen effect when it sees you.

Mechanics and balancing

Running speed

Sneak speed

Stamina depletion and re-generation

AI chasing speed

AI sight/hearing distance

Notice time

This image shows how the value of some of our mechanics affects each other. When it comes to this it is good to be structured, but above all, it comes down to testing and being aware of that/how things affect each other.

We started with extreme values when trying out a feature and then adjusted in smaller steps before reaching the final values.

Tutorial and clues

The tutorial elements in the game are made of paintings and carefully placed in the starting area. This feature got a lot of appreciation from players.

There are also drawings giving clues and guidance to the player. These were playtested and iterated a lot because of their significance leading the player in this open space.  

Some of the iterations telling the player that the key is in a room they probably haven't been in yet.

Design paper drafts turned to 2d artist drafts and later finalized.

A problem was showing clearly to the player if something was locked or open and what the interaction for an object would be. We designed this UI that pops up within a certain distance, shows the type of interaction, and then highlights and conveys how to interact.


The narrative was a pretty big background part of the game. By creating a backstory, character motivations, and a plot with a twist at the end, this also shaped the environment, mood, and gameplay a lot.

It made the game more cohesive, and by not spelling out the plot very literary the player's mind will fill in the blanks or have variations in interpretation.

Get in touch with me if you are interested in how we created the narrative, there are plot and background documents etc, but it's something I'd rather share and explain than upload. 

Level Design

- Create an indoor space that causes unease and suspicion.

- Stealthy gameplay and interesting environment, where you need to hide.

- A 1950s upper-middle-class setting.


I looked into a lot of floor plans and designs, both from real-life houses and from games, especially mansions and horror.

My intention was to find geometry and design that felt "off", suspicious and weird to the player, while still feeling like a home

Corridors without being linear

Different paths


Central design

We talked about the Silent Hill PT demo and how levels that loop around are cool.

I wanted to use space as effectively as possible, having different paths to avoid the monster and for the player to navigate themselves as easy as possible, while not seeing too much

Draft of level

After some drafting I had this general idea of a blueprint.

I wanted to see how it worked in 3d and start refining how the rooms would be shaped and placed, that needed whiteboxing. I used Probuilder in Unity.

General design idea

Iterating on the rooms, using the prototype character and enemy. It needed more variation and crookedness.

The general design is that of a horseshoe where you can take different paths across and between rooms. Rooms are based around the central area and close in proximity. This means you are close to and can hear the enemy more often. Gathering information while (hopefully) being unseen/heard.

Movement and Gameplay

There was a lot of testing and iteration on the composition, how things look, and felt in different positions and areas. Also how it would accommodate free gameplay while still leading the player

We were pretty happy to see that all three jury groups had a playtime very close to 20min.

The attic

The attic was the single most challenging area to design. It is supposed to feel cramped and creepy and an enemy encounter taking place.

You enter at the bottom left. You get a view across the room to where you are going. The area opens up with several ways to hide (example lines). The enemy spawns when you are furthest into the room and you must get back. Hiding places are marked with a circle.

The last bit back is cramped again and it easily turns into a chase. We then despawn the monster when you reach down the stairs.
