Fun enough to play once I learned the rules. It was a good implementation of a fighting system made in limited time (given the author's food poisoning). I liked the sketched-on-paper aesthetic, though (as in known issues) the text is a bit hard to read on the cards, but nothing too difficult. I think with some minimal sound fx it would be a good way to pass some time!
I just realized the name is _Bug_ sumo, which makes a lot more sense than "big" sumo. Ha!
