I'll be honest, I never understood the whats, wheres, and why of the stacking! But I made it through a couple rooms anyways, and I enjoyed the time I spent moving things around trying to figure it out and (especially) watching the little animals bonking through things and making noises.
I'm really impressed with the scope of what you tried to put together! Since I never really "got" the stacking, I felt like I was playing some kind of whimsical, alchemical magic-rules puzzle which made for a unique experience.
