Pretty fun, actually managed to start the car twice :D

Only thing I would add is to be able to rotate by holding right mouse click or by using the keyboard. There is some friction when you need to move your mouse fully to the sides to rotate, would be much better if you could do it more "streamlined".

This was a great game! Fun concept and well executed. I could never get fast enough to try the key. Some times it felt like it wasn't responding to what I was doing, so I wonder if the controls could be tweaked. I could see this as a full game where you have 10-20 different vehicles that you have to clean off and start or you're late for work. Really great idea. Funny how something with a simple concept can just be a lot of fun. Well done!

This is really well done! I like having to swap tools for snow and ice.

Cool idea. I hate brushing snow off of my car. ><

I did want to play a couple of times to see how good I could actually do, so it was addictive a little bit.

For critique - 
I feel like for a mini game, it was hard to know exactly how much my input was effecting my score. It was really cool, just hard to visualize points for a competitive style event. Not saying every game has to be competitive but just mention  it because it was for the field trip.

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!
