You can't close the game via Alt+F4 or via pressing the "X" button on its titlebar.

I just saw this was intentional, but uhh, please fix this anyway. This doesn't prevent you from using the log out button on top of the screen to combat-log, in fact, there's no measure against combat-logging in the game at all, and whenever one is implemented, it should be server-side and independent of the way the player logs out.

Hello HyperSoop, It was made this way in the beginning, though feedback from multiple players was fairly negative about this feature. This is already removed for the new update v0.2.7, allowing players to quit / close the game window in any possible way. Closing this thread now as it is already resolved for the upcoming game update. Regards, Lukas Tokar
