Took me by surprise completely. Loved every detail and stepping on the broken keys was just pure genius! Just saw on the game page you even planned to alt+tab the game with the keys, if that was added my mind would've been blown even harder.
One of my favorites so far, you need to make more :) and if you ever decide to pursue this idea and more features, I would love to try a longer version of it.
Congratulations, lots of praise completely deserved! (And your sense of humor is top of the line).
