Kickstarter date for Subverse was ~april-may 2019 and they showed some game footage there so they already did some work on it in 2019 and probably even in 2018.
Latest movie on their movies page is:
In 2020 there was a "Project snow", a 12 min animation with a "Test Footage" mark that you can find on the webs and not on their website, probably because its not even worth being there, for comparison their usual episodes were 20-30+ mins long so its a good indicator that you cant develop a game and release a long high quality animations at the same time.
Imagine how many full lengths episodes they could put out in those 3 years, even at 30 mins a year that would been a 1.5+ hours of animations that we will never get now. Would Subverse be worth it when it finally releases? I fear it wont be and i dont want to see same thing happening to another content creator that i love.
I really hate arguing with people on internet, its pointless and waste of everybody's time, and yet its exactly what im doing right now
