This is honestly so well made. Not only is the concept great, it's also well implemented too. Making links feels intuitive and all the camera transitions are nice. I could definitely see this being expanded to a full game with larger and more complex solutions. Only real issue is it's easy to just try random solutions until something works, but making players actually think and solve the mystery like intended is always a big challenge when designing detective games. One thing I could think of is having more red herring clues to throw the player off.
Seriously though, I am a fan of detective games and this is one of my favourite games I've tried so far in this jam. I'll be following this project if you end up continuing with it after. Good job :)
