Quite fun! I was wondering if we'd see a circuit-connecting game, with that theme, and this is a great execution of that idea. Something like this could've very well been on the Nokia 3310. I can't seem to get past Level 17, though - there seems to be a blocker in front of one of the plugs?
The Linux version seemingly doesn't want to run on my PC, but the Windows one works through WINE, so it wasn't a big problem.
