[Suggestion] Dark mode and some battery saving ideas

The first thing that comes to mind about this game is that it needs a dark mode for its UI.

Currently, everything and everywhere is in fullbright light color, which starts to hurt my eyes after playing for a while. Implementing a dark mode would be a great improvement, and it could also help save battery life.

On the topic of battery life, I’ve noticed that there are a lot of fancy animations in the game, especially during battles. To be clear, I love the animations during the unpacking and card reviewing sessions, but the number of animations during user interactions and battles is starting to feel a bit overwhelming.

Thus, I hope it could be a optional choice for users to choose if they want to see those animations or not.
