Hi!
Yeah, it will be updated to the Patreon version when v1.3 is finished. v1.3 is currently being worked on and not all of the scenes are done yet, and I don't update the itch version until the update is fully complete.
v1.3 is a rreally big update that adds like four new characters and a bunch of new areas (amongst other things) so it's been in development for a bit but will probably be ready for release in the next couple of months.
Between it being a large update and releasing/developing other games it's just taken a tiny bit longer than usual, but the game is still being worked on as always!
