The update times have gotten slower unfortunately since the start it is a fact, but it is the price we all pay for the breadth of choice and quality/quantity of content. I have played both of those games and have corresponded with with Superwriter (dev of secret summer) many times as a patreon and associate. I am not sure what the team size is for No More Money, but I know Super pretty much does it all himself which is definite props, but it really is apples to oranges to compare us with almost anyone.
Many of Super's games (Secret Summer for example) are static images and no animations (still great and I'm a big fan of his character models, but animations are a considerable time investment he doesn't have to deal with). No More Money does have animations but can and does do updates with no sex at all. Which is something we have never done in my years working on this game. Every update you the MC can get laid at least 2-3 times or more lol.
If we are comparing, most games I believe will push out 150-300 renders an update give or take animations in 1-2 months. Our last several Eps averaged 1k-1200 images, while I'm not as familiar with the amount of coding done by others I doubt many reach the 10-12k lines we have been averaging per EP even when you add up all their updates compared to our longer cycles.
There are some teams out there I can only envy the amount of talent and teams they must bring to bear on their games (NLT/Treasure of Nadia) for example, but I'm not disappointed in anyway in what we do and how much of it and if pareons want to save some money between updates that is fine even if it is a bit sad for our pocket books, but we have our eye on the endgame when we publish a finished product we can be proud of and thankful for the core group of patreons that have stuck with us through it all.
If we manage to expand our team as we have been trying to for quite some time, we might be able to push out content faster, but at present until we find another reliable artist that is a WIP.
