I'm running into the same thing too on this level, where if yellow and green are the same type, even if the green tiles cover the X's the flag doesn't unfurl.
EDIT: Oh I see elsewhere you say everything has to be input. Got it! o7

I played through a couple of dozen levels, and I appreciated the puzzle design a lot.  I felt like each level had a fresh hurdle to overcome and the lesson I was supposed to be learning was clearly communicated.  The art is also super cute!
