That's unfortunate, I really don't have much going on postprocessing-wise. Just a vignette really, so I'm not sure why that would happen, but I'll take a look at that. The level 3 camera should be set at a bit lower height by design, the idea is that level 3 difficulty stems from having to navigate the many chair legs. It should still be at a height where you can see everything pretty clearly though. If it's going through the floor for some reason, I have not been able to recreate that bug. I'm sorry your experience was not what was intended, but thank you for checking it out!
