That's quite impressive for a jam game! It can easily be a demo for a full-size game.
The web player is a bit lagged, a bit of polishment on this side would make the experience a bit better, but it's not a problem, I didn't have critical issues.
One thing that bothered me a bit, was not being able to view what the other characters were going to do, without having to select them. Maybe each character could have a color, and the player could see the action icon with the color of the character that is going to execute it? Just an Idea.
But that said, I'm being picky, the project is so well executed for that short of time! You guys did an incredible job!
