Lovely fun game.
A suggestion/request though: The archive version works when you download and unzip it, but itch.io has their own client as an option for keeping games up to date, and the archive doesn't appear to be formatted in a way that the client can read/install/manage it. Any chance you could look into making Bunny Hunter, and hopefully Bunnygotchi, compatible with the itch client?
There's also a guide that's supposed to help Game developer guide · The itch.io app book - itch.i
