This was a very nice game, congrats ! I completed it.
I liked the music and overall tone a lot.
Unfortunately gameplay mechanics were a flop for me. Combining hints is a great idea but I found it way too hard to find anything. I'm really bad at deduction games though, so it may just be me.
Then I activated the cheats, and it broke the game, with a lot of combination found in the wrong order.
It's too bad because I can tell the writing was good, so I enjoyed the start (when I played without cheats) more than the rest.
I think it would have benefited from a better hint system. Still it's very impressive what you've done in a week !
