Messed around for a little under 30 minutes - here's my 2 cents:
Nice graphics! It looks great, and the animations are smooth. Controls were nice and responsive, and I had no issues trying to dodge stuff.
Gameplay was simple to pick up, and enjoyable, though a little repetitive. Maybe have stuff fly in from more than 2 directions? Animate the characters a little more, or a few costumes/props here and there?
A gauge showing the audience's happiness/enjoyment or total score would be nice. Something to aim for/beat!
Overall, I enjoyed it, but got a little bored after a while. Could do with a little polish here and there.
