Alright, that's an insane amount of custom meshes (if you made them yourself) to do in 3 days, props to you!
Now, unfortunately I will talk about the bad things.
Was Lumen really necessary? It really hits on the performance.
I think the camera image became offset at some point, so I couldn't align myself properly to pick up the last key.
I didn't understand what does the bar on the right do, it was going up and down at random moment. I thought it's going down when I look at something disturbing, but I don't think that's the case anymore, because I was looking at meat at some point and it was holding at the top.
