Thanks for playing! You're speaking our language. We didn't realize the jam started until the 17th, so we were a little short on time. We focused entirely on getting it functional from end to end without any of the extras we dreamed of. There were a few things we wanted to do to make the ending of a round feel more fun, including what you mentioned. We want to make the player change color/shape as you change flavor too.
As for multiplayer, I hope you get a chance to try it out, but keep in mind it only supports local/split-screen multiplayer so far and only if you install the Windows version - for some reason the gamepads don't seem to register correctly on web.
Thanks for playing and for the feedback.
