Okay, allow me to rephrase, the last build of quality was September 2017. The January build was a laugh, and barely worked. I assume that's the other build you speak of, there is no other builds from four months ago, unless you're talking about SQAS, which was not released specifically through Patreon nor is it related to the game in question.
I don't want a refund, I love their project and wish to support it. I've never been one to call this game a scam or a cash cow of any sort. I'd like to keep supporting them, but as stated above, there is a chance the game is abandoned for a plethora of reasons and all the supporters would be shit out of luck. If they start releasing more steadily, I'd be more than happy to resubscribe.
You know, I probably wouldn't even know about this game without this site. So like it or not, forums like this actually give games publicity. It's up to the users to decide if a product is worth investing in.
