*Rurr* Hello! I played, critiqued, reviewed and had some fun with this demo/game, my experience, commentary and silliness is in the video below ;P
Congrats! We concluded you just won the prize for the buggiest walkthrough ^^
Seriously though, we'll definitely get it fixed for the next version as it breaks the experience. As you guessed, the third fuse is located behind the stretcher. Thanks for the review!
