This game is getting a pretty great amount of content I honestly don't understand where you're coming from, 4 updates a month generally with at LEAST one cgi , scenes, updates/reworks. Yes lately it feels like they've been focusing more on adding than expanding but that's a gripe we still get content and it never stops.
Why do you care about what others do with their money lol
Don't know if it's still the case but, when i backed them a while ago (we didn't have the second zone at the time) it was a weird system where you paid your "backer amount" for every update, game or picture.
Meaning that if you took the 10$ backer, you paid $10 for every picture they posted and every update.
So, with 4 updates for the game you pay at least $40 a month, and the amount of pics were kinda random but still adds to the overall amount of money spend by months.
So, even if i agree that we have a lot of updates that adds content (especialy when compared to a lot of other patreon games) i felt like the amount of content wasn't worth that much money, so i stoped after a few months.
So, i can understand why people react that way.
(Also, it's after i stoped backing them that i uncovered this forum)
