Cool concept! All the clutter was chaotic navigate through and definitely made me feel anxious :P
The puzzles were very interesting, though I feel some of them were more frustrating than interesting. The second room one comes to mind; it was tedious to have to search and tally all those tiny objects, especially with some hidden in other objects.
If you continue this I would recommend finding a better balance between challenge and reward for some of the puzzles. You have a really great concept for a puzzle game, just make sure they puzzle us, not punish us. ;P
Nicely done!
