Reminds me of http://nandgame.com and https://nand2tetris.org

Yeah, nand game was part of the inspiration, I felt that it was good but was a bit plain UI/UX wise and obfuscated / simplified some things that it shouldn't have

This is awesome! The truth table lightning round took me by surprise, I am rustier than I thought... One note: It isn't immediately obvious that the In/Out nodes can be connected to multiple wires, made the first few rounds harder to work thru.

truth tables round is optional now!

You need to have a, "Okay, I've tried 10 times, it's not working, what's the answer?" button. That will help not just us rubes who can't understand, but also in the off chance something is broken and even "correct" answers are being rejected.

makes sense, adding to the next push (in the interim, u can also use the copy circuit button to ask gpt if ur correct or not), also, what level is this? (if u dont mind me asking)

Oh that's what the "copy circuit" button does. I have been trying to paste circuits from previous levels into subsequent ones and wondering what I was doing wrong

Hi everyone, commenting to address feedback:

- Made timed minigames optional (e.g. binary tables)

- Added 7 (optional) intro levels to walk through pmos and nmos transistors

- Fixed the bug in the capacitor levels

- Changed editor bg to use dots instead of lines to fix wire confusion

The “next level” button takes you to the next level even if you haven’t solved that level’s prerequisites.
