I find it funny how people tend to get mad at game devs for porn games when in most cases they aren't making crazy amounts of money. Not to mention most of these games are often side projects for Devs who have other projects they are apart of or work other jobs that take priority.
I get the problem people have with projects that seem to stall out but I've supported projects that have stalled out worst then this, but that's because i don't hop on discord to see the interaction of the devs. In the case of Alvein I'm not a supporter so i have no dog in this race, aside form the fact that I enjoy the art and the game itself.
Personally, if your mad as a patreon of a game, I would evaluate your life choices as when you pledge money to a project, your putting money towards promise a game may eventually release. when in actuallity your usually supplimenting someone's side project that can easlily get abandoned because life happens. But what can i expect from those who never grew up to have a life of thier own. don't get me wrong im in the same boat, but I've had enouph shit happen in my own life, and a that side project I worked on, without ever releasing it, fell through. Shit happens and "fans" getting mad doesn't exacly help a dev get thier life back on track enouph to get a release out the door. If it still makes you mad that a project is stalled out, move on to other projects that make you happy, don't dwell on projects that piss you off for whatever reason. someone elses passion project isn't worth getting mad over, there is a litteral sea of games to play on this site, find one that meets your needs. Critic all you want but don't get mad over it. Its not your game, disatification happens, life happens, support what makes you happy because life is to short to be always pissed off. Remember these are just porn games, not everything has to be a personal attack on your morals, you are on a porn game forum after all.
