Nice work, this really tests the patience of the player! I eventually realized that I didn't need to go through every possible square in most of the puzzle levels to get to the end and so it didn't take as long as it probably could to get through the game, but when I thought I might have to collect every single key I was definitely feeling a bit annoyed! But I like how you're playing with the constraints of the medium, skipping through text, hiding keys within keys and the narrative commentary adds a good satirical voice to the project that fits with the theme. I think the pacing is really well done, the levels get more and more complex, each building on the expectations of previous levels, it does a good job of bringing the player through the challenges, there's a reasonable transition from each level to the next.
