nice game! two issues: you can't put down items when you've decided you don't want to use them at the moment, except the brush, and you can't play with those in hand, because it messes up the functions. I tried clicking, space bar and ESC. ESC takes you to the home screen, which does the trick, but it's annoying.
another issue, after which I stopped playing, is that on a Mac, you can't rotate the sign leading to the toilet room, so can't continue playing past this point.
