Yes. There is also a downloadable file for the sfw version too. It's on itch.io, just below the description / info. Most benefits you can access on my patreon are downloadable. Maybe the browser version I uploaded confused you?
As I mentioned before, the earnings I receive monthly from Patreon go directly into the production of the games (The artists, musicians etc). Since these are episodic games, a subscription system works very well with this format. I can continue to release new episodes thanks to all the subscriptions, and people can keep playing them. You, of course, are free to not like it personally, but this is what I feel most comfortable doing as a developer who wants to keep making free to play games for everybody to have some sort of access despite their financial situation.🙂
Going "poof" over time is unfortunately a serious problem of today's digital content. Platforms like Steam are included in this digital "renting" system. So, not every downloadable content is archiveable either. This is especially serious in the mobile app industry. Which is exactly why I like Patreon, because it gives developers more power over their own content. How you distribute, how you contact with the people who support you is completely up to you. Feels like I'm advertising Patreon, but as a creator, I'm really really happy with their platform and I think most people misunderstand how it actually works. Basically, the people who can afford it help those who can't access the content that they feel are worth it. ⭐
Feel free to join whenever you like. I do hope you will enjoy it, if you do! 🙂
