Don't know if this belongs here or on hints but I'll post here.
When playing the game, clicking on the light bulb is supposed to show all the items that can be picked up. Well, I click and nothing happens. There is also a keyboard shortcut with the tab key but still nothing. When I click it just gives me a message that clicking shows the items that can be picked up but it doesn't show them.
You laugh because I'm different
I laugh because you're all the same
Funny I don't remember being absent minded.
