Can't forward with W in BlakeStone: Aliens of Gold

[nicedoomer35]

On Windows 11 Home I have bought the game BlakeStone: Aliens of Gold, via GOG Galaxy (only about 1.25 USD).

My problem is that I cna't go forward with W and backwards with S because W is already taken by the game's software to make agent Stone turn 180-degree.

I wouldn't care to somehow totally get rid of this 180-degree turn because it's not part of my playing of the game; I want to play more Doom-like, where there is no such 180-degree turn at all, rather, only strifing.

I have already tried forcing this from Xbox Mapper (via CTRL+F1) for W and it worked but bugged the game (no shooting sound, enemies don't notice the shooting, etc.).

How to ensure that the keys W and S (with or without Caps Lock On) could use me to make agent Stone to go forward or backwards?
