No, the game is abandoned. The creator is making a comic that will tell the story instead. The story will be the exact same, which is why the comic can be seen as a continuation of the game, but the game itself is no longer being worked on.
Of course! The creator's Twitter handle is @moonrunes3 and while they have posted the available pages there, they also made a dedicated website. https://glassmindmanga.carrd.co/
They're currently working on page 3, but their main focus lies on creating their Homestuck spinoff.
