I believe you can see all of your purchases on Itch, if you go to My Library, then My Purchases :)
The information we share on our Itch page is the same as on other pages. Our Steam Store pages probably show off the most for each specific episode.
You are welcome to ask any specific questions in our Discord server, too.
We also have a website, but it is a little outdated now, we plan to update it later this year to include more updated information.
