Right off the bat, this was my kind of dig, dog. Having wasted years of my life playing Lego flash games, I knew I'd like it as soon as you pulled out the transistor puzzle piece.
The set dressing and environment are fun, as is the narrative stitching for why we're here. You puzzles, rather than just being a shaken-jar of "guess the number", very clearly reflect to the player what their objective is, and promise it can be achieved by just playing around, engaging, and seeing the results. A lot of people miss that gamespace between "victory" and "defeat" that's supposed to keep the player going, and seeing the little animations and timed fuses helps convey to me when I am or am not on the right track.
I think the visuals could use a little more gamefeel. I think adding a snap-grid to the pick and place would make it feel a lot more responsive and purposeful to the player. Combine that with some free time post-jam to make the cable a little droopier and sloppier, I could see you reinforcing both aspects of mad-man and genius that you're trying to make the player feel. Many UI elements just didn't hold up to your excellent standard either.
I was so happy when it started clicking and I could see all the different permutations of numbers I could achieve with just a few tools. I think the concept, the models themselves, the content you created is all up to fantastic stuff. I hope I can see more clever games from your team. xx
