First, the game description is a fabrication. There are no hallways to explore in this game, no logic and reasoning. They’re numbers on the screen, same as seen in MDF. Each day, a new puzzle: four digits for four boxes…search for the 16 individual digits needed to complete the file! Easy, right? It was great fun until I began to realize that most levels have at least one needed digit sitting just outside the invisible boundaries of the puzzle. There it is, just wigglin’ around, wanting you to press on it but you can’t! If you splurge for the $.99=5hints deal, the hints even guide you to these inaccessible numbers and yet you cannot activate them, leaving every level woefully incomplete. It’s almost like they built in the frustration on purpose. I’ve fully completed 2 levels; dozens of others sit at 88% or 92%, with the remaining needed numbers just out of reach. Why?
