15 Single-Player First-Person Games You Need to Try Out

Viewfinder 

Developed by Sad Owl Studios, Viewfinder is easily one of the most creative games in recent memory. The game tasks players to solve puzzle rooms by clicking images, placing them into the game world, and watching them magically become a new part of the level. The game starts out simply with easy puzzles, but it eventually ramps up in complexity as you delve deeper into this mind-bending adventure. The story might not be all that entertaining, but the fresh gameplay ideas and head-scratching puzzle designs are more than enough reasons to keep going.
