I enjoyed puzzling together the answers, probably because of the nice artwork and the overall polished feel to this game. Kudos for having a very clear solution, i.e. being able to come to the one right conclusion with the clues just by deductive reasoning. At the same time, the solution was not obvious or could easily be brute-forced.
One thing I did find a little frustrating was looking for clues as I was missing the last two in a place I had looked at time and time again without realizing there were more clues to click at. Also, in the very beginning, I felt a little lost as to what to do - clicking the phone was obvious and the animation helped a lot to guide me but was followed by a "now what?" moment.
Overall, the experience felt just right and I hope you keep adding more in the future. I'd definitely come back and play some more.
