LAST SHOT is an murder mystery game where you photograph your own home to summon your dead girlfriend's ghost, who appears in the frame and gives you real-time AI-generated images to solve her murder. The key innovation is using Nano Banana as a bridge between the AI-generated ghost and the player's own personal space, creating an experience where the story bleeds into your real life. Finally, the verdict judgment itself is also powered by Gemini, which evaluates how many evidence elements the player has successfully identified and incorporated into their conclusion.
