I'm stuck. There's a locked door that says "Seems it needs a switch to be on." The only things that seem to be interactable are four lamps, but no matter which I turn on, the door stays locked.
Hey mangoduck, thanks for trying out my game.
That puzzle is definitely the hardest and in a future update I'll add hints to make it easier.
But for now-
(When turning on the lamps, pay attention to the right side of the screen. Something is affected by the lamps.)
Hope this helps!
