Woah surprisingly really fun. I was wondering how you could even lose as Tic-Tac-Toe is a 'solved' game, but adding a time constraint and juggling multiple boards at once was fun in a rushed and anxiety-inducing way. I only got to playing one run, but the 'combo' attacks from frenzy was super satisfying especially on groups of enemies with an almost complete board. Lots of creative and interesting abilities / enemies that I wouldn't have even thought of adding to a Tic-Tac-Toe game, but it made it feel fresh and exciting. Definitely not a 'solved' game.
