Kuviu: You're on a timer, remember?
Right. Your imminent death. It's a little hard to believe that you're actually in danger, since you know things will work out all right. Even the big meteor is just a pretty falling star right now, and the smaller fires are still far away.
Pnimm wasn't able to tell you what you're looking for, but luckily there's not much in here. You go look at the yellow platform, which seems vaguely, comfortingly familiar, but jumping on it doesn't produce any results. Neither does the purple one. So that just leaves this round white thing, you guess.
