​Alan Hazelden in his Thinky Third Thursday article:

"Blaž Urban Gracar is the mastermind behind LOK, the puzzle book which then spawned our very own LOK Digital. He's returned with another puzzle book which I found just as delightful, in which you'll help ghostly workers to find the right path to construct specific shapes. It's not easy but nor is it as intimidating as it might first seem, and I think it does a great job of keeping you on board even as it pushes the concept further and further."

​Onee-Fin's blog post:

"Workworkworked through all of Workworkwork by Letibus / Blaž Urban Gracar (the guy who made LOK and Abdec) today. It’s extremely awesome and i cannot recommend it enough. Do be warned: it’s pretty tough! Without spoiling too much, I can say that mechanically, it’s clear early on that the concepts introduced have the potential to get extremely complicated, and while the puzzles do push the envelope to some really mind-bending levels, the setups all have a good way to get pieced together through a few key logical insights. It was really fun to never really feel like i was totally lost and had to trial-and-error until something worked, despite the mechanics seeming super like they would be that sort of experience. Just really solid, really smooth, really hardcore puzzle solving."
