Normally patches like that are free.
Even <2 bucks is way to expensive for a patch that doesn't work and there is no money back guarantee to try it.

You're right - and if it was just a patch to remove censorship, it would be free! However, it adds additional content to the game and is a DLC of its own with dedicated updates, bug support, and major content patches. If you decide to try it, we hope you enjoy it!
As far as trying it to see if you like it, we recommend checking out uncensored let's plays, player reviews, or asking members of our Discord community (https://discord.com/invite/eekgames) before you spend the $1.54 to purchase it! You can always refer to GameJolt's return policy, too, to make sure you can return it if you decide you don't like it and want a full refund of the money spent!
Have a great day and an awesome holiday!
