Anyone who likes this should also take a look at: https://store.steampowered.com/app/1444480/Turing_Complete/ At the end you have your own CPU with your own assembly language. Sadly stuck in early access since forever with some very rough edges

I can also thoroughly recommend https://store.steampowered.com/app/684270/Silicon_Zeroes/ which uses smart design to remove having to deal with binary in the circuit design. This reduces complexity by a surprising amount.

This reminds me of the Zachtronics game KOHCTPYKTOP ( https://zachtronics.com/zach-like/ ). The game left me wanting more and wishing I was using an actual tool for learning or designing semiconductors circuits, rather than playing a game.

Wow, I didn't realize Zachtronics made Infiniminer. Fascinating!

I am a huge sucker for games/lessons like this. I feel like I've played one every 5 years for the last almost 25 years.

There is more! In Last Call BBS they made another circuit builder: https://store.steampowered.com/app/1511780/Last_Call_BBS/

Bro. I'm obsessed with this. I spent a good 2-2.5 hours on a trot with this. This was one of those things I always wanted to learn a lot about and this was just perfect for that. It wasn't that easy, I really struggled and gave up on some levels but came back and struggled through them. The HexRacer type levels are difficult and I wish I could skip through those.

Also when you give a solution, you probably need an explanation of why that works.

Can't wait till you add the additional coming soon levels.

Your feedback feature seems broken. I tried giving feedback about some basic bugs and it kept saying can't send message.

Please also add a waitlist to notify when you release the additional levels.

I love this! I learned my first logic with Crocodile Clips: would simulate and solder a lot of D flip flop based logic before learning about microcontrollers (my first was Atmel AT90S2313)

This is amazing. There are a few quirks here and there, but the idea is great and it's super fun to play around in.

I was able to do the latch level (2.11) using a single OR gate. It did pass the tests, but I am not sure if what I did actually works in practice. (Force as one input, then feed the output of the OR gate into the other input) The fun fact after completing the level mentions a bistable latch (I don't know what that is) using two inverters, which I didn't use.

Awesome! Small feedback: The test should maybe auto run. I solved the first level and was confused why I didn't proceed. The out was -1 (but goal was z) and it took me a while to see the 'run test' button.
