So using the Rage bullet, I managed to get one boss to kill another boss before I'd "detected" the second boss. Now I've got an objective to kill a boss that's at 0% life that's not marked as completed. Bug?
...Broke it. Got a Sweet Impact in Survival, but when it landed it didn't explode. So I was this giant ball of cotton candy rolling along the ground, hitting maybe 1/10 of the gummies on the ground. Only things that affected me were bombs (speed up), and doors (speed down). Then, when I finally ran out of speed, the music stopped playing, and I couldn't click "Go Again" or "Shop". Reloading the page, I can't click Start or Survival. So now I can't even play.
