The game is super dynamic, it is one of the main advantages of Eclipse Duel. You have very little resources for battle and you need to think wisely how to use energy before you will face intense combats.
Actually as it revealed there is even some plot which gives you some basic understanding of what is even going on, but unfortunately it is only implemented in terms of reading some kind of recordings.
The potential is crazy, hope devs will not abandone the game.
