Since it is our first Steam game, we are very unfamiliar with the Steam launch process...Currently, the game is still in Steam review, and the review time has exceeded our expectations (we thought it could be reviewed in 1-2 days)
At present, the game has been in review for almost a week... I hope that there will be good news soon, and we will release it as soon as the game passes.
Thank you very much to everyone who followed, and very sorry for the postponement
