Attempted to play this game, none of the controls seem to work, aside from WASD movement and the Esc menu.
I'm playing on Linux via WINE.
If you're talking about the first level, movement is all you need, you don't get access to the full controls until you get past the tutorial in level 2. If you're having trouble past that, please let me know.
If you need a hint for the first level, you can push the TV stand down from above. I need to make that more clear, sorry.
