Thank you for your suggestions! ๐
I intend to add new characters after finishing some steps. Some has already appeared in the game xD
I think I don't want the game to be neither too long nor too short in gameplay. Considering it already has about 2h of gameplay, I'd say it should be about 5h so you can complete the story of a character and about 8h to complete stories of everyone, I guess. No idea ๐ Only guessing numbers.
I expect to update until it's no longer beta and is full playable. Then, put on Steam if I can and start to update it as a full game, just adding contents. Maybe, mechanics like corruption, appearance customization and things that could add more details like routes and arts may be left for this stage.
