A mobile game, at most
Wow that was boring. I kept hoping I would lose to get out of it. Why is this a full-blown game mode? Random drops are always a terrible and lazy design. The so-called "tactics" mean very little when you can't control what you get. The controls are bad, and it needs a practice or bot mode for those of us who haven't played games like this. I read the tutorial, but it still doesn't make much sense. Maybe try fixing the millions of bugs and unbalanced game play of your main game before you try branching out.
This game would make more sense on a mobile device. It's something I might play during lunch at work. It's too dull to play on my computer.
