This is an excellent idea for a 20 second game and the artwork and audio feed into it perfectly. I wasn't able to make it very far into the game because right-clicking doesn't work well on a trackpad. Some tweaks that could help might be making the highlights blink so they are more obvious and even make them float in front of the tools you're using for better visibility. Some audible/visible feedback on completed tasks would be good so you know, for example, when you have successfully unbolted a wheel. This is a solid and fun idea and if you plan to continue, it would be great to see it develop.
