I like this, currently stuck on the level with the three arrows and (P) and I've managed to tangle two wires so that they are stuck crossing each other and I can't untangle them. I've already spent several minutes trying to untangle them. A "Reset wired" option that just removed and respawned the wired would be useful for me here, as is I don't think I have the patience to replay all the previous levels just to get this level back as it started.
Promising game though from what I've seen so far! Could probably have a little more hand-holding or explanation for the early levels. If you don't read I and O as "Input" and "Output" but as "One" and "Zero" you could get quite confused (as a friend reported to me after trying it).
