A Main Character

In OTXO, you play as an unnamed protagonist wearing a black suit and tie along with an opaque white mask that completely covers their head. They are referred to as "The OTXO" while wearing the mask. (The word OTXO means "wolf" in Basque.)
Not important information, but this game is meant to both a fun and entertaining experience as well as a metaphor for fighting depression; or whatever inner demons you may live with. I specifically refer to the main character as a they/them because this is anyone's journey.
====== STORY ======
In the beginning of the game, the main character is seen sitting in a train with his girlfriend. Sitting on a seat across from them, a man looks around to see if anyone is watching him before getting up and tossing a white mask on the ground in front of the main character on their way out. The main character is compelled to put the mask on, and picks it up. After inspecting it for a moment, they put it on and seemingly faint in their seat, only to wake up face down on a beach. Dressed now in a suit, and unable to take off the mask, the OTXO got up and looked around to see nothing but a mansion in the distance on what seemed to be an island. They proceeded towards the mansion to find a groundskeeper sweeping the porch, unsurprised at the OTXO's presence. The groundkeeper answered some questions that the OTXO likely had, though the OTXO never speaks. Where were they? How did they get here? Why is this mansion here? Along with the questions, he handed the OTXO a rifle and told them to follow him. He took them into the mansion, into a sort of training room, and taught the OTXO the basics of survival; how to make it though the mansion- or at least try. The shooting and maneuvering came natural to the OTXO, and the groundskeeper gave the green light to proceed further into the mansion, wishing them luck.
[Events onwards are as the game proceeds. I personally refuse to spoil the game, as it is a journey, and not an easy one.]
===== SKILLS =====
The OTXO has natural combat abilities, and their functions are as follows.
Kicking: There are few melee options in the game, but kicking is one you always have. Kicking (MMB be default) will kill in a single hit on enemies, bosses not included. The main use is killing enemies that get too close, and "opening" doors.
Focus: This is an ability given to the OTXO by the mask, and when activated (LEFT SHIFT by default), slows the game down to bullet time while the OTXO maintains decently fast movement. The ability is limited in duration, but recharges over time. This is incredibly good for engaging multiple enemies at a time and avoiding/escaping danger and should be used whenever it feels necessary.
