Thank you. I can't help but feel the wall textures have screwed the whole thing. It might be that they've tried to just be too clever with this and a less complex solution (flat shading, gouraud shading) would have worked better.

Yeah I had the same thought. I played a few FPS on my ti-83 back in the day, it was black and white, and really it only drew the edges of the walls and outlines of people. But I could tell pretty well what was going on in comparison to this.

This atari game might also look a lot better on a crt or something.

If you reduce the window to a very small size (or look at your monitor from a few meters away) then it's actually easier to see what's going on.

I wonder how it would look on a CRT TV over RF.

It's difficult for me to tell if the player is looking at a wall or a hallway...

Maybe it’s a wallway

It's a bit unclear what's demoing visuals vs. gameplay. It seemed often that when the player reaches a corner, instead of turning the corner and continuing down the corridor the player would sometimes turn into the corner and wiggle. I wonder is there something about corners that's a bit janky or is that just a habit of this particular user that they sometimes just turn left and right randomly particularly in corners?

The gameplay is quite interesting; I noticed the upgrade on the game. I hope I have enough time to try the game out.
