I liked it! It reminds me other this other game my friend made (also about monkeys and typewriters), but you took it in a completely different direction that I feel is much more interesting, making each monkey type out a possible word, than having all monkeys combined type one word. https://pyrousha.itch.io/infinite-monkey-theorem-real
It did find some parts of the game confusing at first, such as how to piece together quotes. Also, I don't think I could buy the tier 2 upgrades for some reason.
But overall, good job! This is a really good concept executed well.
