weirdworld (the creator) said so himself
you should go check out his patreon since it takes him some time to update the itch page
if you want the update as soon as it releases then you can pay only five dollars a month (or less if you pay annualy) to recieve access to the update a week earlier and recieve acess to devlogs which are updates from ww about the next update and his current life as well as access to preview posts of new characters and monsters
