Great job! The starting cutscene is really charming and gets you into the setting.
It is actually a programming game under the hood haha. Here are some feedbacks that maybe could improve the game:
On the looping bar, there is a big red thing and some knobs on the right, but they did not react to input, It feels like the don't do anything and is just aesthetics? If so, It would be great to make them call for less attention (specially the big red thing). They could be more grayed out, for example, and all pushed to the far right.
On the programming game inspiration: one cool thing on grid based programming puzzles games is that once you figured out the solution, you can play in x4 speed to just see the result. But when you have to wait for a slow song for like 1 minute just watching and thinking about nothing is kind of a drag that put me off a bit. Usually the fun of a puzzle game is in figuring out the solution, less in the execution, and much less in just seeing the execution play out for a long time. I don't know exactly how you can solve this downtime as it uses the theme of a music looping. Maybe there is a slow puzzly sound when you are experimenting, but when the player gets the loop right (and the game indentifies it), change to a super energized rock song that goes faster and the player can feel the urge to flee from the guard. Maybe this could add some change of pace to the feelings of a level too, which could be great.
I hope these constructive feedbacks can help improve the game :)
I also made a rhythm/music game haha, so maybe you guys might like it too o/
Great work. Cheers <3
