Great use of classic mechanic to both made it narrative and encapsulate the theme. Love every second of it. And surprisingly tough as a puzzle as well. Will definitely be playing more of it! 

I loved the art and the audio! I'm a sucker for little puzzle games like this. It would have been great to have the phone call have information for the logic puzzle, like a script written that have them saying clues more conversational style "Well I saw him lurking around" "when was that?" "Early in the morning"

i love the sound effects for the typing so satisfying, you could maybe built in a hint system for the first game? maybe? the second game I didn't really understand

also I did understand after a while that the right puzzles get slightly transparent but you could explain that transparent mechanic the first time it happens (a small text box just saying that...and then disappearing again) and maybe you could built in a hint button with how the image is supposed to look like. At first it was really hard until I saw the screenshot below.

the hint image could disappear/ be minimized if u didnt intend to obscure your nice art :) but maybe you could've even added a toggle if u as a user want the image to disappear or not while playing (because it really makes the playing much more enjoyable if you at least the goal) otherwise kind of hard

Nice game, but honestly I wish you put some kind of spin on the puzzles to make them more unique and fun.
