They were supporting him with $2000 a month until he stopped updating his game and stopped communicating with his patrons at all. When he goes radio silent for months and follows it up with "sorry the thing you wanted is on indefinite hiatus give me money to make new thing", these "braindead wastes of space" are not obligated to keep paying him, and they are perfectly justified in being upset that the money they were putting towards this particular project went nowhere.
Oni and Brakus never stopped communicating, patreons were up to date with everything.
2K a month it wasnt enough for them to go Full time (both of them have families to feed), so normal for the updates taking a bit more time to drop and with them having to work a real job aswell with effect the development, there was also some miss-management here and there with ambitious implementations.
Their new project is focused to make enough income to continue DBA production, who know perhaps dba will go same path has the new game if it sell well.
It easy to complain and point things without valid information or know about stuff around here,
at the end of the day everyone wants the project to continue but nothing is has easy has words.
