Bug: The cat will always drop the key, even after the first time.
And I think I ended with 60ish on the run I was exploring everything. I gather the final secret is something that can be found if you have 50+, or the feather, because I am fairly sure I waited there for the entire day early on and nothing happened.
Anyway, all in all this is a fun use of multi-purposed code. Lots of reuse and variable usage but it's done well. I laughed at the one creature that was added in to be able to reuse the elephant's script. Heh.
