Really cool premise and presentation but like other commenters have already mentioned the RNG's influence is still too strong because you have no control over when you attack.
I really like how the audience is drawn (and the au-die-ence pun) and the animations for when new members are added. The curtain effects for when the game begins is also extremely slick, especially in the WebGL version where it lines up with the page banner.
Really cool premise overall, just needs some fiddling. Please consider continuing work on it post-jam!!
