Saw this game on Mark's stream today, and then I gave it a go.
Very fun to play, with easy puzzling.
My one minor recommendation would be to write how much those resistances take from you, instead of just color coding them. While dying isn't a big deal, as the levels are short, it still is a trial-and error in the end.
Apart from this, I'd love to see if you would introduce other electronical components into the mix, for a more complex set of puzzles :)
Cheers!
