It's always nice to see educational games like that. A lot of new learners (like me) are just looking at the high level stuff, where the computer "just works"...

Well done and keep it up :)

Love it, thanks! Would you mind making it possible for me to see my "circuit" after running the tests? Currently, I can't go back to the circuit I created.

Fixed!

This would be such a good game for introducing students to digital technology! This is so fun! We just had to draw them by hand back in the dark ages of the 2010s.

Thx, way better (imo) than just reading slides or (god forbid) pure text describing comp arch

100% agree - the way that you have the very subtle arrows on the transistor drains that show the actual current flow is really smart too. I struggled with visualizing the current flow in undergrad for an embarrassingly long time.

as a learning resource, it would be great it acronyms were expanded at least once. nmos, pmos, gnd, vdd all in the first 5 seconds or so, and i didnt see anywhere that actually said what those stood for

otherwise, looks polished and fills in a nice niche!

Cool concept, but it should be mobile friendly

Earlier quoted context omitted.

Sure, you should be able to rn though, is this after completing the level (wanna fix this bug)?

Sure, but I can't seem to find the git?

I haven't pushed to github (Will do this soon), but I believe that i've fixed the issue (also, by wanna fix this bug I meant I want to fix this bug, (but would def also appreciate help if ur interested, the mechanics of this game ended up being a bit more complex than I initially envisioned lol))

No problem. I am currently on the third level I think and my laptop fan ramps up, so I closed the tab and it stopped. Also, how can I delete e.g. transistors again?

Good point (I didn't really consider this), might be a bit difficult tho tbh, but i'll push this soon

This looks really cool, although I personally seem to lack the absolute basic knowledge that is required to make sense of the tutorial messages, so I couldn't even figure out the first level.

Glad I'm not the only one! I love these kinds of games; played the heck out of Turing Complete and Zachtronics' Engineer of the People... But I'd never heard of 3 state logic until today.

Really threw me for a loop! I'm still trying to wrap my head around making level 3's NOT gate.

This is such a cool idea, definitely the first 3-state circuit puzzler I've seen! Throw a cute story over it and I bet this would get some takers on Steam.

I see, I'll try to reduce the load, i'm using canvas 2d so that could be causing it. you can delete by selecting then pressing the delete button (will also allow right click to delete in the next push, since i do this for wires)
