My partner and I played several enjoyable rounds of this game together! (It's right up their alley because they love when they get to go CHOMP in games.) It was very enjoyable finding out various things about how the chomping works (you can chomp your own pieces! two pieces that would chomp each other instead swap places!) A very fun twist on Tic-Tac-Toe and my usual strategies definitely require some re-thinking here.
My only suggested improvement is it'd be good to have a new game button (and that the full black-white spectrum *plus* the full white-purple spectrum is not really monochromatic).
I will probably be coming back to this one to play more in the future! It's very satisfying.
