This story is very well written, with a lack of typos and grammatical errors. The action scenes in particular are visceral, captivating, and entertaining. The variety between paths was also very cool, with a number of different settings(Spoiler - click to show), and even going so far as to have different main characters in each path.
The plots themselves, which vary by path, are intriguing and fitting for the very short length of the game, are mostly satisfying wins, and each is properly fleshed out.
Surprisingly (and unfortunately), there aren't that many monkeys, but this doesn't detract from the story in any way.
Overall, this is definitely a game worth 20 minutes of your time, and is an outstanding piece of short fiction in a CYOA format!
