Really badass puzzle game, a perfect balance of the theme for this jam! I only had a few gripes, but they were worth working through.

My first issue was the reference board. I didn't know the reference board behind the desk existed at the beginning of the game, so instead of referring to the first note I received, I had to alt tab out of the game to access the reference I needed in one of the game's screenshots. I was getting mad because I thought the references I was grabbing were disappearing to nowhere! Then, the character references the board with information on it for a different puzzle. Perhaps he should have said "Ahh, a note, I'm putting this on my reference board just above the desk" the first time he got something. Or, the game could have started with the camera entering the room with a full view of the room before sitting at the desk, and with a different note than the rest (probably a briefing) on the board so you're forced to interact with it before doing anything else.

Anyways, the other gripe I had was with the musical notation. I know how to read music, but it isn't so much use if I completely lack a clef to work with! Is it treble or bass clef? I was having a hard time matching the notes up with the ones on the paper, and I realized I was defaulting to treble because that was the one for the instrument I know, but it could easily be bass clef and I'm none the wiser. Also, some of the notes on that paper were very ambiguous, like I'd see two notes on the thing and they both look kinda like a G, but one note is higher or lower than the other but not all the way off the line so I wasn't sure. It was distracting me and making me a little upset... but nonetheless, I guestimated and still managed to win

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!

Wait, developer! This is the game design police. You've been arrested for accusations that your ECS game doesn't pause, but closes the game window. We'll get away with a warning this time, but don't do it again.

Great idea. I love puzzles, but you accidentally managed to put together exactly the ones I'm bad at – Morse code and music :)

Anyway, it was interesting. The only serious issue is the lack of a truly fast rewind feature. Realistic, but inconvenient :/

The music track itself is good, by the way :)

This is so creative and on theme! I was not expecting a deciphering game at all! I'm a huge fan of detective stuff and I really enjoyed this :D 

First of all the game looks really good, on the gameplay side it absolutely has some fun and intriguing puzzles. The only feedback id give is that considering how much goes around listening to the tape in certain way it can get somewhat frustrating not having more control over the tape itself.

Great sound design and very serious, I just wish there were a couple more hints, I only got one when I was trying to brute force a certain puzzle and it wasn't quite enough for me to solve it

 :(

Also, the tape seems to stop and not be usable if you go past the start or end points?
