Thank you! I'm glad to know someone else has these kinds of unsettling dreams that are not necessarily nightmares, but just very ominous in retrospect. I agree tank controls work so well for walking sims! Adds like an extra layer of depth to the walking, you know?
The game is made in Unity btw, I used Modus Interactive's PSX shaders, but I recommend using the Haunted PS1 Render Pipeline! The skyboxes are just tiling images put on a canvas at the far end of the camera's render frustum that rotates when you turn. The PSX shader also had the option to only render things from a short distance and cut it off per polygon which gives it that nice crusty low render distance feel. :)
