Neat concept, very unique take on the theme which I like. I enjoyed rolling around as a rock lol. The sections where you move the table and the ladder were great ideas, and with a bit more time I'm sure you could make some great puzzles with this line of thinking.
I think that a more ambient music track would really elevate the package - and I fell off the map one time and my progress got reset (wasn't sure if it was intentional or not).
Overall, it's clean, focused, unique, and has the potential to become something bigger in the future - great job :)
