First Person View
First of all, we'd like to tell you more about our ideas and thoughts regarding our decision for the first-person view. The idea of creating more immersion by seeing the game directly from the main character's perspective also allows features like inspecting objects to place more emphasis on exploring the environment.
One of our goals was to expand the game's existing role-playing elements with first-person adventure elements to make the environment more interesting during gameplay and encourage players to examine everything more closely, while also being rewarded for doing so.
Making the Player Character Visible
There are various ways to represent first-person mode. In many games, for example, only the player character's hands, weapons or arms are visualized, but not the body. This clearly has the advantage of saving work and animations for the representation.
On the other hand it's better to be able to see your body when looking down on yourself, to create as much immersion as possible. We ultimately decided to actually represent the player character visually, including its movements and, of course, the chosen weapons, to enable a more immersive experience.

Shadows
This decision has another positive aspect. If you place the main character in front of a light source, such as a lamp or torch, a shadow of your own silhouette is cast onto the wall or floor. This gives you the feeling of actually immersing yourself into the game world and isn't distracted or pulled out of the action by unrealistic visual simplifications.

In order to be able to empathize with what it feels like to walk around in the shaft and be exposed to various, sometimes even scary, situations, it is important to us to implement features and new game elements as immersively as possible.
Thank you for your interest, see you soon!
