Played this with my wife and it's a lot of fun. Both the punchy action and doing it on the same controller. I guess technically the same controller thing is a bit of a gimmick, but it just makes this feel like thumb fighting, which really adds something to the experience if not to the game.

My only criticism is that it's possible to instantly win if you face away from the other player while grabbing the knife. I think that could be easily fixed by always enforcing a minimum distance between the players equal to the knife length, even if no one's holding the knife.

I also see the lack of multiplayer game testers has hit you guys even harder than us (we also went for local multiplayer). Sorry to see this has only three ratings, it's a really cool game!

Had to test this game by myself, but I think I kinda understood the gist of it.

The idea of having a single weapon (and a single controller) for two players is neat and original. I really enjoy the controls of the crabs, always facing the weapon, that's fitting,  pretty unique and yet easy to understand.

The possibility of knocking off the knife is interesting, but unfortunately, from what I tested, it also means that the weaponless player can become invincible just by spamming the trigger. That kinda breaks the whole game! Maybe you could add a bit of timing control to it (like if you hit the button when you're about to be stabbed you send the knife flying, but otherwise you don't)?

Also, overall I feel like the game lacks a bit of juice. Maybe add some visual effects or change the music when one player picks the knife? You could probably make that knifey crab a bit more murderous than it is to add some fun!

Anyway, that's a pretty interesting game, some more polishing could make really good!
