After emailing Itch about exactly how to get Defend from Candyland!'s Steam keys for sale on Itch, they have responded and I have done as they ask. Now, you can purchase Defend from Candyland! through Itch and receive a Steam key, giving you full access to all 120 tantalisingly sweet but difficult levels of this difficult Tower Defence game!
