I really like this game! It is so nerve wracking when the time is running out, and I haven't gotten close to clearing the door to put the key in! I was sweating!
I like that the key is optional and low points, especially when it wasn't a highlight of the instructions. It would be super cool to expand on the idea of "where are my keys" by hiding the key in the snow on the car somewhere XD!
I found it really interesting that the mechanic of removing the ice was very specific, and that it was kind of subtly hinted at in the instructions below (see "respectfully"). You kind of need a gentle and slow touch, compared to the snow that was fast and easy to brush off. I liked that a lot!
