This was really fun, if a bit short. The mechanic feels very clever, and it melds nicely with a puzzle adventury atmosphere. I also liked that there was a bit of added complexity with the items you have to collect to get to certain places, though I'd have liked some more of that sort of thing -- i.e. things that make the puzzles a bit less straightforward to solve? But I think the map zooming as a core mechanic is really good.
The game also looks and feels great; nicely done!
