Mountains of Despair won't level up

[JJ]

I've gone through the mountains of despair without losing a zoombini about 10 times, and it still hasn't levelled up from 'not so easy'. All the other sections are on 'very hard' and it's really really annoying. Does anyone know why, or is it a glitch?

Sorry to hear this. I'll report this to our developers.

I had this problem too. I think I figured it out.
At Bubble Abyss, the last Zoombini through isn't registered until it takes it's place in the line. If you press the go button too quickly, then that last Zoombini gets left behind and it doesn't count that you got all 16 through. I had a Zoombini that I thought had made it to Zoombiniville waiting back at the rest stop because of this.

So, after the last bubble pops make sure to wait a couple seconds before proceeding.
