Hey, thanks for playing the game and leaving a Review.
Well, there is no Tool to break the Ice. Turning up the Heat is the first Part of the Solution. The Fridge just needs some Time to Heat up. So mybe there is a way to skip a few hours. (The Fridge Cogwheel is the second one btw. So you need to solve another one first)
Well, if this wouldn't be a Videogame where I know all the Answers, I would also be a very bad Detective xD
