This game is still in development, but let me give you a brief overview of the current planned roadmap:
1- Subscribers of the "RokumaruArt" Patreon will enjoy early access to the game, allowing them to play segments of it before the official launch, as they become available, in addition to the regular Patreon content featuring exclusive illustrations.
2- Once the entire game is finished, it will be released on itch.io at its full price.
3- Starting from that point onward, game updates (including bug fixes, text corrections, etc.) will be implemented in the itch.io version.
