This dev works in bursts, and releases big updates from time to time when those bursts occur. Come back in half a year or so and the entirety of season 3 will be out by then for sure.

He took an entire year to do a .5 release which was barely a few scenes, some of which weren't even finished. The "features" he claimed to be working on hardly work and are literal entry level programming.
I love the game but the dev is lazy and content to just ride on the patreon money like so many other devs. I will absolutely play every release but I seriously don't expect the next chapter for another year at least.
