***SPOILERS AHEAD***
Cool idea and mechanics. Of course a lot could be improve in the matter of presentation but in regard of the gameplay I liked the game a lot. What I find could be improved would be the design of the puzzles. I mostly ended solving them by process of elimination instead of by logic. I no expert in detective games and couldn't solve sh1t in "Return of the Obra Dinn" but still couldn't find the solutions satisfying:
On the first one I failed to see why the lamp was the murder weapon, I started with the flower base just because it was the closest one to the husband and tried everything until I got the lamp. But couldn't really find any logic or indication. Also I don't understand the narrative. I'm guessing the wife was cheating and the husband killed her? But if she got caught why is the other guy still hiding in the closet. And who entered by the window? The lover? Did he just sneaked in to f*ck while the husband was in the house? That doesn't make any sense so I'm guessing the husband came back early from traveling. Somehow saw the both from the window and entered from there? A bit of a stretch that's the only reason I could find for the footprints outside the window. But if he saw them then again why the red guy still in the closet. I don't know seems weird and not at all satisfying.
The rest of the cases are really similar, at the bank robbery a fifth guy was the killer but I couldn't really find any evidence of the fifth guy existing, and he didn't even take the money so I don't know what that was about.
And at the third there was just to many options so I couldn't solve the case solved by elimination. I may just be really bad a these games or maybe the puzzles and narrative need a lot of work. Either way I like the idea and could certainly see it working after a bit of work. Keep it going!
