Really happy to know you have enjoyed the game. About the seasons, chapters and releases... Well, there are people here who can tell you better about it, but this game if my mind doesn´t fail was developed by two people, one of them left and then the project was taken only by Ocean. He has been working alone all this time (i think he continues being alone) and the first season "suffered" a remake, or if i´m wrong and it wasn´t the whole season then there were several chapters affected, this things spend soooo many time.
Yes, i know what you are thinking, 6 YEARS FOR THAT??? Indeed, there have been others problems related with Patreon, Steam and other music rights and that stuff, and Ocean is very fussy with his work, is perfect or he doesn´t stop (not a bad thing for me).
We have too the renders he makes like specials gifts for special holidays and those things.
I have said all i remember about why the project is really slow, even the first chapter of the season 2 is going to be massive, around 6.000 renders (more or less). One chapter for year is the objetive i think, or at least, i hope so, is slow, but very good stuff (imo).
That´s all i can say, i´m pretty sure other people here is better informed but i wanted to contribute
