It was a great experience!
My biggest issue was with the logic gates. If I hadn't been familiar with them, I'd have had a hard time figuring out what each of them did, due to the vagueness of the symbols. Also, some crossing paths lead to the belief that they were joined, when they weren't. But once I figured these out everything became far more enjoyable.
The puzzle difficulty was excellent, not easy nor annoyingly hard.
The reuse of mechanics was smartly done, from a design perspective.
Headphones definitely enhance the sound department, specially with the ASMR-like whispers and general echoey ambience.
The inclusion of a playable tutorial was a nice touch!
