Superb work, kweepa!
Does the Bullfrog Puzzle on level 4 work? the buttons don't seem to do anything.

I just checked to be sure and yes, it does work. The dials control the position, then the upper button raises the floor at that position and the lower button lowers the floor. The buttons and dials work the same way as the other buttons and dials, press Y to activate. You should see the dials rotate and the buttons toggle in and out and hear a scrrrreak sound. To check if anything has happened, you may need to climb down and run around the area inside the moat of water.
By inert you mean they don't even slide the little nodule in and out? I'm not sure how that's possible. There's no connection to the plot or any dialog. Switches can't be disabled. Can you try it and send me your player.log from %APPDATA%\..\LocalLow\Kweepa\UnityUnderground please? (To stevemccrea at gmail dot com)
I had this same issue (Nothing would happen on the grid when I pushed the buttons, even if I used a stick), but then it just started working later in the game. Ironically I only found out because another puzzle in the same area broke on me - The silver/gold switch door. No matter how many times I try the correct order, it won't open.
I found the issue with the Bullfrog puzzle, thanks to someone sending me a player.log - the wand needs to be on the same level as the switches, or on a level that you have visited since you loaded the game. I have fixed it locally. I still haven't found what is wrong with the silver/gold switch door. It doesn't rely on any other object, so it's not a related bug.
