You can use the itch.io app to download it (or go to my FA or discord that are listed in the credits). For whatever reason itch.io's website does not currently allow playable online files to be downloaded unless you download it using the itch.io app. itch.io's website allows older files to be downloaded when there are multiple files or when a game is not playable online. Additionally, patrons of my Patreon have download links for the next updated version of the game (Dragon Watching Version 1.01 which will receive a public release sometime in a future month).
