Liminal Gallery took me about a half-hour to beat. This is a well-functioning recreation of Viewfinder's main mechanic. Almost all of the puzzle concepts are borrowed from Viewfinder, so there's not much new here. The movement is slightly unpolished and the picture placing isn't as seamless as in Viewfinder, but these are negligible nitpicks. My only dislike with the game is the fact that the player is required to walk through repeating pictures to progress multiple times. It doesn't make sense within the rules of the mechanic that self-repeating pictures would somehow change at some point. This is a mistake that Viewfinder doesn't make.
