This is excellent, both educationally and from a UX standpoint! I've tried multiple times to read explanations on how transistors work and bounced off, but this time I think I've finally understood how to use them, at least practically. I feel like this is a great continuation of https://nandgame.com which taught me quite a bit about how small circuits combine to form something big (although I never finished it, I hope to finish this one at least). Another thing that I find interesting, is that while it is clearly developed primarily by AI, the result is exceptionally better than nearly every other AI-assisted project I've tried.

Some suggestions: - What I miss from NAND Game is the challenge of optimizing for efficiency. You'd build a component and it would let you know if it could be built with fewer NAND gates and you'd try to simplify the circuit. For example, while I did "NAND it" with 4 transistors, I did "The dual" with 5 and given the explanation I got afterwards I could have used one less. - This definitely needs to get better on mobile - The description for the first level using BitLine and BitLineBar (I think that was the Sense Amp?) doesn't really explain what it's supposed to do and I had to deduce it from the truth table.
