Is a animated by hand game (altho no in 1080 but still) it seems like Dev does "loses time" doing extra art, but this level of quality takes time, when have you seen another game this beautifully animated huh?
with how technology is as outdated as its always been, the progress of making these games never gets any easier for developers.
we got morons like Microsoft making a mess of things and so on. if only technology had more legitimately useful software out there that made the struggles of doing dev work less straining. we could make games like this massively improved. also don't forget about the scumbags out there that make money yet another hoop and hurdle to get over.
like itch for example making the developer wait. a properly built system, app or site could have had this issue resolved instantaneously.
