Cute game which I had fun beating but it got a bit confusing at least at the beginning. I didn't see a reason to bet more than the 5 ante. I don't know if choosing your symbol has a timer on it like the betting phase, but I at least FELT pressured to pick quickly, and probably would have have a more natural time betting if it had just been Rock/Paper/Scissors, as we're already trying to figure out which choices give more biscuits, so might as well make the choice of what beats what feel more natural.
I think it's really neat to combine a gambling mechanic with Rock Paper Scissors. I'd like to be able to do something like this with other real people who I could fake out emotionally, but netcode is definitely an extreme piece of feature creep! Good job nonetheless!
