This happens because of two reasons : 1) Those who'd been supporting me for one or two month unsubscribed. I have no complaints with them, they're great because every single $ helps us to keep up the development. The 50$ patron who helped us a lot turned 10$ and here's the loss of 40$. Still, we're thankful to him and he did more than we actually deserve. 2) The fraudsters. I'm talking about those who subscribe at the beginning of the month and then when they receive the game, they unsubscribe. Wel'll get rid of them soon. This is a temporarily problem connected with the patreons's payment system.
All in all... well, that's how I get supported. It's sad but I move on.
The stories of all characters will evolve in parallel. You'll choose soon enough with whom you want to finish this game.
I don't want to stretch the plot. I understand that the visibility of the impact of love on patreon. But this is a banal deception. All the author's tricks to increase sales of games, I know. I don't want to go that way.
