Ouch.
To be honest I was rather skeptical about the whole development considering they hadn't released anything meaningful since January. Just yesterday I was replying to someone on YT about how risky Patreon and Kickstarter projects are - just because you throw your money at them doesn't guarantee a release at all, and that the whole system works pretty much like a fair-chance lottery with very little consumer protection. It sucks to see one of the best funded ero games bite the dust... hopefully this will serve as a lesson, both for the consumers and the developers themselves - 1)be careful of who you trust and 2)never give someone you barely know too much power with little consequence, specially if they live far away. The thing with internet connections is that it gives people a special sense of security that extends to "hit-and-run" tactics - if they screw up or feel like dropping out on an important project, its very easy to do so with little consequence.
Besides, what HBomb is doing, although understandable, is bordering on 'illegal'. He/she is basically inciting someone to attack S Purple and ruin whatever future projects he may have and possibly even endanger his life - because the internet is full of crazies who will shoot you just for saying the wrong thing, stealing thousands of dollars from them will only make it even more 'justifiable' in their minds. Airing your dirty laundry like this with a passive-aggressive attitude ins't the best way to get people on your side either, no matter how right you are... If S Purple is unreliable and untrustworthy, HBomb seems to be vengeful type that will get back you for doing the wrong thing - not exactly stellar images to have as a developer either way... but that's just my opinion. Besides, if things have been going like this for a while then why didn't they inform people about what was going on? What if S Purple hadn't said anything? They were receiving more than 30k per month so it was their responsibility to say something... or at least put an halt to the project... but they didn't. Because it was convenient to their wallets.
That aside, as much as I like the idea of supporting indie developers, situations like these HAVE to be stopped otherwise the trust level between both parties will drop so low it only hurt the entire indie market and anyone who relies on Patreon + Kickstarter to make a living.
