I returned to this after like a year and now only have two or three (I think) lasers left.
It took me long enough, but I finally discovered what the black monoliths are about (thank you bamboo forest) and completed a few of the environmental puzzles and Wow, consider my brain fully bent.
I just love the shit out of this game. It’s so relaxing, and the feeling of discovery when you find a secret, or solve a panel after staring at it for two hours, is pretty unparalleled.
