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.
