Being Detective Conan is required to play this game, it's a simple fps puzzle game, I loved the intro arts, the only problem i found is the texts size and GUI, which are too small for my eyes (not sure if it's my laptop issue)
i think the concept can be remaked into a more deep and complex game, i prefer to translate the concept into a 2D game instead of 3D after i saw the arts quality, that's my honest opinion.
best of luck for you all ;)
cheers.
