If y'all would scroll like two pages back, you would see the answers from the dev. Like "the core is completed".
Thanks for your answer, but the question was if the game is completed, why remove the completed state then?
After being completed, games could get improvements, bug fixes, etc... but the completed tag remains.
Maybe the dev wants to dig more in the story and feels that it shouldn't be considered finished anymore?
Or maybe some parts of the game still need some significant work or polishing?
If it's the later case, it's understandable, just to prevent bad reviews (like the last one), but if it's about adding new content to extend the game, I think it would be wise to let it as completed (if the story is actually finished). Completed games attract more people and it will serve as a good advertising for the the next game already ongoing.
But it's just my opinion.
