Are you asking for a subjective opinion? Personally I hated it, in fact I've found the last few updates in particular deeply disappointing.
That doesn't change the fact that he
did produce those updates (making your 2 year statement an outright falsehood) and nothing in his Patreon promises "n" amount of updates in "x" amount of time. He has always been slow about how many updates he produces (approx 2-3 per year normally, and like most Devs he gets slower as time progresses and his game/story become more complex)
Yes, I think you were wrong to beleive rewarding poor choices would improve things.... not sure what else you wanted me to say to that?
Stupid may be the wrong word, but you certainly are very confused if you thought you were owed anything more... Support Devs that you think
ARE producing things worth supporting (Tipping a Busker is an accurate analogy) . Don't mistake "supporting" with "buying". Maybe a better way would be to think of it like adopting a child, that child might take all your gifts and make you proud... but he probably won't (children are all assholes
).... At least with Patreon it doesn't need to be forever, as soon as he disappoints you you can just send him packing again.
