Ratlab!

You! Yes, you're the lucky one to have successfully undergone a highly experimental procedure to significantly increase your cognitive abilities! But before you leave the room, those respectful and totally professional researchers need to make sure that taxpayer money did not go to waste.

Ratlab is a single-player first person puzzle game where the player is a test subject in a lab.
