Is my green shell level really so difficult? Only one vgc member beat it I believe.
I think it got regulated to an expert mode course because it's hardly getting any playthroughs right now

I didn't want to play through the rest of it lol.  I did find out that the green shell from the beginning isn't absolutely necessary as you can still grab one of the red shells on the spikes.
