I love these kind of multitasking challenges, and this one was designed well!
My only complaint would be the TYGH squares mode, I think the yellow indicators approach the squares way too slow and they are really difficult to parse because so many of them get cramped together.
But otherwise I had tons of fun (and suffering) playing the game, great work!
I’m late commenting but I did manage to get my rating in before the voting ended ;)
