Steam and Itch versions will be identical. (Only difference I guess is that Steam has achievements) Both fully uncensored.
Current plan for pricing is 11.99 USD base price. Discounted to 9.99 USD for the first week. I used Steam's regional pricing which looks at different countries' average income etc to determine price. So depending on where you're from it will be cheaper than 9.99.
Let me know if you have any other questions!
