Fun story! Chuckled at the not-too-uncommon "I'm the owner" cat jokes.
I found 3 different endings (spoilers below), is this all of them or I missed something?
Ending 1 - find the cape, don't trick the cat, and get to choose between becoming the new Greenmother or growing up in the garden. I chose the latter, but I assume the former is the same as ending 2. (Also, I believe there was no "The End" and the end of this one.)
Ending 2 - don't find the cape, and run away from cupboard, ultimately failing to save Elsa or bring back the Tear. Become the new Greenmother.
Ending 3 - find the cape, trick the cat, and return with Sun Tear. Stay in the garden to learn further.
