How is it outrageous?
The amount of work that is involved in making updates with a small team, the quality that's put into the game is why it's one of the top games on F95.
They also have lives where there is sickness, family events, holidays etc.
They keep us well informed weekly of the progress made with charts and weekly streams, they don't disappear for months on end with no information of what's going on. If there is a delay of some kind they keep us well informed even though we are receiving the game for free!
So even if was 10 months or more there is nothing outrageous about it, they are doing great and I look forward to the release of the next update.
