i got it yesterday before bed and woke up to read it was gone but still got to play it. i wouldnt say its the worlds fastest. but pretty dang fast. i did it legit and took me about a hour until i couldnt complete the hardest puzzle because they give you like 4 tiles that all look the same. so i looked at a guide and finished it. if i looked at a guide to begin with you can easily plat this game in 5 minutes. so depending if you use a guide or not it can be the worlds fastest game.
