Great atmosphere with the sfx, music and visuals really coming together!
I agree, that the game would benefit from a bit more guidance - some kind of map to unlock as you progress perhaps? Also something like being able to pick up connections and re-connecting them elsewhere to fix any errors made because I didn't know how to reverse my actions. A tutorial note inside the game on the controls, perhaps in a settings menu (including volume sliders too).
Other than that, it's a functioning game with polished visuals and sfx. I can see the generosity aspect, perhaps some story text as you solve the puzzles would really cement that :)
