the game trailer maybe coming in 31/10/2023
After the game release it might have some updates to fix erorrs or add a new feature to fully complete the chapter 1 story if there are something I forgot to do on the main release so there is a, "updates" menu in the main menu. It's have no updates when I first release the game. If there is, so it mean the you have own the update version.
thank you for reading :)
