At one point, on the last level it let me play (or-gate) before going to the KS pitch - I had components on the screen, and I was able to move them around without the wires following.

It was moving two of the components around (even though I only had one selected, iirc), and when I dropped them, the connections didn't follow, but the circuit was still working.

There was also some weird end-points of the "wires" created (extra nodes or whatnot). At one point I clicked on one of the nodes that was already wired, and the wire reappeared.

I'm not sure if I could replicate this issue, but there is definitely something not quite right that needs to be checked out.

All in all, though, I liked it! I wanted to keep playing...sigh.
