You could draw the artwork yourself and make your own game, just sayin...
I'm seeing an average of over 100 sprites added to each SU Unity update, and even when 'just modifying' a number of those, that takes time... and who knows how many hours that SR7 spends trying to 'debug' the stuff he's setting up using Fungus...
There are over 11,000 sprites in SU 2.3.95 btw in case you were curious.
Hearing SS and SR7 talking about the SU Unity framework, it sounds like a house of cards that's ready to crash at any moment, which is why they've been adding new locations that don't rely the scheduler screens and such, to avoid those 'minefields' when they can.
Setting up new locations 'divorces' those locations from previous dependencies, so I can understand why SR7 is taking that approach by setting up Themyscira and such.
Fungus may be an 'easy' tool to use, but it's far from perfect. And from what I was able to glean from the twitch stream interview, SR7 is set in his ways, and likes to do things old school. Stubborn-ness and all that.
I don't consider over 100 new sprites in each update a 'trickle' just sayin... For some developers, that'd be considered a lot of work. And if SR7 needs to take two months off every year to recharge his creative juices, well he's been doing that for years now so it's not a mystery.
Again though, you've already dropped your Patreon support, and are now acquiring the games by other means, so you made your choice and no longer support them, which is how these things work. The Patrons that do still support GS Games know what they have 'bought in to' and that's their choice, not yours. As I pointed out, they are supporting the GS Games studio in it's various forms, not just SU Unity.
