Small chunks are actually great for impatient people(which, judging by comments in some threads, are at the very least an incredibly vocal minority).It's actually kinda annoying when a game receives tiny chunks of updates once every 2-3 months. This game is a year old already and so far it's ver 0.09 .. Imagine how many decades or centuries it would take for the dev to finally complete (ver 1.0) the game.. I'm guessing the dev is planning to leave behind this project for his grandchildren to finish
This dev took about 4-5 years to finish their previous(and first) game- the f95 thread appeared in 2021 and the game got released in 2023, plus for some time before 2021 updates were only available on their blog(going by my dodgy memory, at least another 2 years). I would expect a similar timeframe, especially since this one is made on a different engine(Unity) compared to the previous game- if they stuck to the previously used engine we could have expected a somewhat shorter development on account of dev not having to relearn engine from scratch.
At this point, patience is all we can and should have.
