Thank you so much for your kind words! I also love that TUNG's only logic component is the inverter. It means that everything is built from the simplest of principles. Zero abstraction makes the circuits so conceptually beautiful.
However, for the sequel -- Logic World -- I've decided to include more high-level components. You get built-in XOR, AND, D-latches and a few others. I thought long and hard about this decision, but ultimately I think it adds more value to the game than it removes. That said, I'm planning to have a 'hardcore' mode which restricts your logic component selection to the TUNG set.
As for shrinking/abstracting boards, I don't want to add this to vanilla. I really like that the game has you building sprawling, building-sized machines where you can walk up to every individual part. However, Logic World has great modding support, and board compression could absolutely be added by a mod.
Thanks for playing, I'm glad TUNG brought you some joy :)
