Hi!
Passed 8 levels, the game is fun, simple, but unfortunately I don't see how it corresponds to the theme. It gets a bit boring after a while, maybe it would be a good idea to add a time that you have to complete the level to keep the player interested. The sound is pleasant. When threads cross, an alert is displayed, I would like something less rigid :D. In general, a good game - congratulations!
P.S.
I read that you wanted to make electric circuits, then the question about the topic was removed :).
