Speaking from the perspective who has spent 100s of hours making detailed mods and stuff for games,
To me, if people are paying for the Patreon, then they're entitled to be upset or wanting faster updates. If you're just getting it from this site and moaning and berating DPC, then just grow up, it's a game/VN, if DPC wants to take a year for an update to ensure its good quality, he is well within his rights.
Do i want to play more, of course, but let the guy work at his own pace. If he rushed things to get it out quicker, people would moan. When working on stuff creatively, you can choose between quality or speed. Add in personal issues, and he's probably been burnt out at some point, it's a human being who makes this stuff, not just a robot that spams out work and has nothing else going on in life
