Is it still worth playing?

Fireproof Games' puzzle game, the fourth in The Room series, released for mobile in January 2018 and for Windows in February 2021. It is an escape the room game in which you examine a highly detailed dollhouse, find its secrets by manipulating objects and solve its puzzles. Some puzzles involve the Null, a material that warps reality, and a special eyepiece lets you see objects made of it, revealing hidden objects and puzzles. If you get stuck, you can ask for a hint after a certain time, with no penalty. The puzzles here are interconnected across several rooms: water pumped into the kitchen has to be heated to make the steam that drives equipment in the workshop. Each room holds an artifact as its prize. The one house still feels like a small connected place, because its puzzles connect from room to room.
