About the chests… that’s actually a bug, XDDD. I already knew that, and it will be fixed in the next update.
Yeah, battles were too easy, I think that in the early stages of the game, there haven’t been enough alternative equipment and skills introduced yet. In this situation, making battles too difficult wouldn’t be appropriate, so all the fights are fairly simple, there’s still plenty of room for improvement…
Overall, thank you for playing! Your suggestions are very insightful, and I truly appreciate your feedback!
