The light puzzle after the first one had a different pattern, yeah. It affected lights diagonally adjacent to the light you were interacting with. I also get the thing about the console a lot. If I had the time I would have looked for sounds to use to alert that a change was made, but could not because I stressed out on time. If the game had the lore I initially planned for it to have, the darkness mechanic would have made sense; there is a monster that killed your friend while you were in space, and it is trying to kill you, and it is only alive in the dark. If you would like any assistance on the game, here is the Walkthrough. https://www.youtube.com/watch?v=K6WucsdJnaQ&t=171s
And also thank you for the kind words. I hope to remake this with my own assets and with a larger diversity of puzzles, as well as (hopefully) some cool ass lore.
