I think everything looks and sounds good. Took a moment but figured out how to play I think. It doesn't seem like color matters, only connections (could be wrong on this), just connect two power sources to same circuit blows up the circuit. Works well. I think it just needs to be messed with more to feel fun.
Right now, I can easily just keep making small connections and keep blowing them up, If you move things wrong, there is no way to get out of it, so maybe some mechanic that lets you remove wires like wire cutters or something.
Great job, so far I think it is one of the most polished games I have seen so far.
