Looking at his patreon posts, he's been drawing 2-3 pics or pixel art each month for the last 2 years.
Taking a month off here and there, pausing the billing and being opened about it.
He finished the art part in may and has been slowly working on writing the scenes and scripts.
After 5 months of story writing now, I'm guessing we might get an update before the end of the year lol.
Since he started the game he got a wife & kid, makes me wonder if she's ok with him doing a shota game or if he's only working on it when she's not looking.
