Hello, this is GM Carrot.
We have discovered a symptom of not being able to access the game since a few days ago.
As a result of the verification, it was identified as a problem caused by the instability of the Steam server.
Apart from this, our developers are working hard to find a way for a smooth access.
We will do our best to provide you with a smooth game environment as quickly as possible.
Once again, we are so sorry for any convenience.
