Very interesting game! Once I got how to control everything I spent some good time in this museum!
The only thing I can propose is to add some effect on the camera, so it look more like a night vision camera, it would add a lot to the immersion.
Yeah, I wanted to do that, but the green ambient light I added to the environment somehow didn't render though the secondary viewport and I ended up debugging other stuff. I'll give that another look after voting ends. I wanted to start looking into shaders anyway, so I hope I can get a more crt style too. Thank you for playing ;)
