So, the game is functional, but not very fun. This is a fantastic first step. The battles are simple. You lose, then you win. Not much strategy. I would have preferred this to auto battle for me. As in, clicking "Start Battle" wasn't worth it.
My suggestion is to make it harder, make success incremental, and then increase the people you fight. Maybe tiers?
Thanks for a comment. I'm thinking about adding more strategic elements to the combat. I also feel like the difficulty needs to be a bit higher. I'm hoping for player matchmaking with the database linked, but since there aren't many people yet, it feels a bit too simple. The tier system is a great idea too. I'll work on developing that further!
