I seem to be having the same problem as a few others - I'll click on something, or press a button, and all elements disappear. I have to start the level all over again, which is somewhat annoying now that it has happened every single time I play the third level. Can't get passed it! Fortunately, I'm happy trying to play it through anyway :)

 "Killbot!"){kind=icon}
I'm pretty sure I've fixed this in the version I just uploaded. It took me forever to make it happen on my machine.
