High praise

The atmosphere is great, the over growth in the beginning and the rundown testing chambers feels very post-apocalyptic in a way that feels as if you're felt forgotten. I was on-edge most of the time, even the explosion took me by surprise

Tricky but rewarding when completed - great job!

The last chamber was a bit of a challenge, but I got there in the end.

I am not clear on the challenge. Do you mean you can only move three cubes? Or only use three to re direct the lasers? I clearly see how not to use one at all, but if the goal is not to touch two of the five cubes I am very curious of the solution.

I do not like this test because nothing made me think the solution was always obvious it was just tedious to get to it. The test looks great visually though
