Hi everyone! First of all, we want to say a huge thank you to everyone who has been supporting us. Since launch, we’ve been keeping a close eye on all your feedback. We’ve been hard at work making adjustments and optimizations based on your suggestions to make the game even better to play.

• Save Anywhere: You can now manually save your progress at any Sacred Firebowl you find in the game.

• Load Game UI: We’ve added a new "Load Game" screen to the Main Menu.
