People are not complaining about the game, they're mostly complaining about direction this game have taken. I mean you dedicate whole update on a rework and don't bother to bring in something new. 4-5 months has past. Then you break old saves so players who had played before are forced to start over. No thanks. I tried to start over but simply i don't wanna throw 2-3 hours for some rework scenes. And why people will wait for next update you might ask, its because the game is actually good. Of course if v.17 will be another rework i doubt that there will be anyone who would play it or talk about it.
As I see it, even if it's rework and story don't progress a bit, it's still something new as those arts weren't there before. It's still work for Oseo, it's still new arts for us. About redoing everything for you what you can consider being nothing or very little, I might agree, but dunno as additions seems to be bugged even for new saves I sticked to my old saves so it doesn't bother me here. And there's pretty much everytime a good samaritan to upload a save.
There's still the sempiternal question "does free users are legits to complain ?", I can hear that everyone can express an opinion and I don't know the portion of users complaining here who actually supports/supported Oseo (yet we saw many times that people who got something free complains the most) and there's a point to it (bring more people to support your work, have some more visibility). But I also agree that if you want your complains to be heard, you have to invest something other than your time in the product, and that's the creator owes me nothing as I haven't paid for his work.
