Doom is ingenious, but it is not terribly complex IMHO, not compared to a modern networking stack including WiFi driver. The Doom renderer charm is in its overall simplicity. The AI is effective but not sophisticated.
the “app logic”/wrapper pieces come out to about 25kb
WiFi is 350 Tls is 120 and certs are 90!
but 100kb you’re not gonna see :) this has WiFi, tls, etc. doom didn’t need those
however, it is really not that impressive for just a client
> built out of redstone in minecraft
Ummm... > 5 million parameters
Which is a lot more than 888kb... Supposing your ESP32 could use qint8 (LOL) that's still 1 byte per parameter and the k in kb stands for thousand, not million.
