If you're reading this, this game is not abandoned.
Well, this build with the old engine is gonna be abandoned, but the dev is continuing the game on a completely new engine because the engine and models used to make this older game is outdated and doesn't work properly on new PCs. Game will be continued on a new engine.
Edit: I'm gonna make this clear, it was the dev himself said that he was working on the story in a new engine in this comment section which you can find it and I decided to make a comment about it to spread the news. I don't know where to find their progress or any reports they have, I don't know what engines the dev used for their games, I don't know if this statement is even true at all. With that said, let's all hope for the best for this game.
