Good job! I think the generation could use some improvements, and adding more restrictions for the player would make the game more interesting—for example, limiting the number of wires or preventing loose wire ends. It would also be great to have an option to undo wire placement.

I encountered a bug while playing: after several level restarts, the game stopped responding to wire selection buttons and would only place one type of wire on the field, regardless of the selected option.

Also, it would be nice to have an exit button, even if you don’t want to let us go! :)
