As long its not 1-2 years long its fine.
People might as well respect what the dev's are making.
But if it was for 1-2 years long wait with no public at any point during the year, then you have the right to feel worried about the direction of the game. Because no way am i gonna wait a hole year for a game that goes Patreon builds in a row, but no public.
Well its... really-really close still.
From 2.4 to 3.0 we only got like 2 new scenes with the fox girl only and literally nothing else(basically a "wakeup scene"), not even a line of new story. It toke 6 months, no new extras at all.
The next update is relatively close, but it toke another 5 or might be 6 months, and the update will be... 1 new scene and some combat, + drag and drop puzzle...
Sure, there are updates... but there are games that do more in 2 weeks, than this game in a year.
Considering there are 5 more characters, by just the time every character gets 1 single scene will take 3 more years. The story, extra scenes and such are going on the top of that, not to mention that Foxy said that he plans it a fairly large game, if you only take it as 2 scene / character then we are already at a 7-8 years development time.
And that is only if Foxyghost keeps up the peace, we seen countless times that projects gets slower significantly when the motivation goes away a few years in, or often completely abandoned... Quality is good 100%, but we also seen way too many of these stories to just ignore them.
TLDR: While the game isn't abandoned, you are far better off treating it as it IS abandoned, and at best revisit it a couple of years later.
