I legitimately burst out laughing (in a good way) when the first enemy unexpectedly ran off with a piece of my grid - partially because, from the text description alone, I was unsure what they would be trying to achieve and partially because the animation's walk cycle is fantastic!
Really had fun playing! My one piece of feedback would be potentially adding a timer or something similar, to let players set and then beat a personal best of keeping their Grid. But that's feedback from my style of game dev and I totally respect if you'd rather not have it in your game(s)!
