Loved playing through green hell. In my opinion, the food/drink/leech/worm/insanity/venom all being "too frequent and too unforgivable" is right on point. I would expect to have these same issues if I were dropped in the middle of the rain forest. This forces you to think ahead, and be prepared for what can go wrong in the rest of the game. However, while I understand the need in story mode to not let us cut bigger trees to make bases, I would love to see this in survival mode, where we can clear land of bigger trees to just build and survive.
