It's a compact, linear pointcrawl with a good setting choice. Every location is well defined and easy to use.
I have a doubt about a phrase: in Area 2, it says if you distrub the pollen you Lose 1d4 INT and 1/hour for one day DC12 CON or slip into a beatific stupor. I am not sure how to read it you mean you lose 1d4 int now and 1 point per hour if you fail the save? That's a lot... perhaps it's missing something and you lose hp instead? Not sure, would appreciate an explanation.
