In the next update, I plan to add an "Escape" skill right from the beginning so you can exit mid-battle. Also, you can press F5 to force a quick reset back to the main menu! As for the short text during fights, I made it fast because I was worried that longer text would become frustrating when players have to retry boss fights multiple times... I hope you understand. There is no set release date yet, but I am aiming to release the next demo update around July. Thank you!
