I faced the same problems as the other two reviewers. Couldn't find the box with the letter lock (and ended up with scanning each screen waiting for the cursor to change) and I had to watch the walkthrough to figure out Gilroy – if it's meant to represent the WW2 drawing as Stefanielouise says, then I believe it's spelt "Kilroy". No medal here either – the "medal unlocked" popup shows up, but the medal doesn't get unlocked.
I often wonder how certain tasks in your games can somehow produce a key out of a nowhere. Tasks like watering a plant. Feeding a squirrel. Or putting three pearls on a bracelet. That's the kind of thing which drags down the quality of your games towards the generic escape games the portal is filled with. Your games aren't just few screens cluttered with out-of-place clues and puzzles; they're better! At the very least, you are consistent and loyal to your setting. So why always not to logic?
This is one of your shorter games, no need to nitpick further, but what I appreciate here though, is the explanation in the beginning (exploring & twisted ankle & no cellphone sounds definitely better than "you woke up in an abandoned house and the door is locked.") Also, thanks for getting rid of the redirect in the end.
