Completed Sanitarium.
Switching to a four-handed goat-legged Conan-like creature that fights giant cybernetic insects was certainly an inventive moment.
The music puzzle completely trashed me, though. I figured out that the children are singing the six notes you need to input. But for the life of me, I couldn’t repeat it.
Funnily enough, most of the walkthroughs get this part wrong as well.
Besides that, though, I managed to beat the game without looking into the guide. Which is an achievement for the game designers. Usually get get stuck in point’n’click adventures early on.
