In their defense, they just impatient of getting a public update, since the Patreon builds take priority.
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.
