You can check out our Patreon, for instance, every tier has an explanation of what version of the game you get. $5/a month will land you a previous uncensored game version and 10$/a month (the most popular option) will get you the latest and uncensored game build. $20/a month will guarantee you a Steam key when our game launches on Steam.
If you don’t like the subscription part, there are other options as well. You can get Deluded directly from our itch.io, but keep in mind you have to purchase the versions separately (if you get the version 0.3, it doesn’t mean you are getting 0.4 for free). That being said, on itch you only pay for major updates (0.something, not the 0.3.5, for example) until version 0.9. After that, it’s going to be “pay once, get it for life”, just like on Steam. At this moment of development, we can not put the game on lifetime ownership.
Lust Launcher is just an alternative way to get and launch the game. It has been experiencing some problems lately, so I wouldn't recommend it.
