I'm a sucker for apes. Some great ideas in here and I love the premise. 

This is a fantastic adventure setting that perfectly captures a classic pulp, sword-and-sorcery feel. The backstory of the ape-god Barong, his usurpation of a cosmic entity, and the forging of the Obsidian Artifacts is a strong and evocative premise for any campaign.

The design provides a great sandbox for exploration. The factions are a real highlight; the conflicting goals of the ambitious Goblin King, the secretive Serpent Priestess, and the dutiful Ape Vampire Lord create a dynamic and dangerous political landscape for players to navigate. The random tables are also concise and useful, providing all the necessary tools to run an extended jungle crawl.

The entire document is a great example of a usable and inspiring adventure toolkit.

For a last minute entry, this has a very clear, unfussy structure. all of the elements that the GM would need to run an adventure are here- after all we’re all imaginative folk, tell us the big bad is an ape vampire lord and we could interpret that. Where we’re going we don’t need no map- the table saves you time and gets us there. All in all, I think this is a fun adventure, a pulpy animal book that Kipling would recognise. 

Your outline has decided Appendix N potential.

I read you did it in the last minute, but I think that overall it's a nice plot, with some juicy ideas.

A very interesting premise, but I missed a map to navigate and explore the fantastic locations you mention. Some images of a creature or two would also be nice for the adventure. In any case, it sounds like a good adventure to me.

Well laid out. Some interesting enccounters like a  Vampire Ape. I think adding art would really beef it up. 

Good job.
