I found the part where they said they're going to release it on steam after they were done with 1.20. But I was curious on where they said on the winter release because I cant find it.
Sorry this was my bad, I miss remembered people speculating with the developer actually saying it, I've been going a bit to their ci-en page and I don't find it, really sorry for the missinformation.
Here is some info that I got
23rd July, the developer mentioned that its time for them to start working on steam version, and in the they said that the project is worked by a "publisher?" and its gonna contain both english and simplified chinese.
25th September, the developer is focusing on the steam version of celes and other things, as well taking injections (assuming covid vaccine because japan is just begining to give people vaccine around 1 to 2 months ago) and taking a break. And in the comment section they said they are working on it right now, its still gonna take some time but please look forward to it.
The things that confuses me is they mentioned giving the project to publisher, and now they said that they are working on it. If they gave it to a publisher means that they are not the one working on it right? Idk probably what they meant is they are now working together with the publisher. Take this info with a grain of salt.
So the release date is not confirmed yet, but they are focusing on steam release, so hopefully its not gonna be that long. Its hard to play it when it took me 1 minute to read a simple japanese line and the mtl is really not good to play with.
