I'm still wondering too. The last update available here on Itch was released in January 2022. It's like the developer has completely abandoned us and just releases new versions to Patreon.
Viewing post in If I buy will this gets updated or do I have to buy again
That was actually an accident but i just decided to ignore it. I hope if people download it they understand why those releases don't come to itch. Having to buy every item in the shop to start playing the game is not fun. It's like that not cause I want it to be but so I can get feedback on the function and bug reports.
