I love these kinds of puzzle games! Very immersive and diagetic. I have zero ear for music, so the notes puzzles was hard for me, but I was soo satisfied picking up the morse code through the music in the first bit to figure out the lock. For the map, though, to be honest, I just couldn’t pick it up by ear, so I ended up guessing every coordinate combination until it progressed me :x
I got the answer wrong at the end cause I couldn’t figure out how to pick. I know I had to use the music-letter map but maybe I missed something.
Regardless, fun game! I do wish the rewind wasn’t so slow, or that there was some volume option (maybe even in game on the tape recorder?) but other than that I had fun. Well done, seriously!
