Decent tool for 1st year students. Are the card positions random in subsequent games?
Really not a fan of this game. If you just want the card, let the tutorial run itself a few times while you do something more interesting. You'll get credit for the kills.
Much too slow. Smart cursor control such as click to move and click to use attack that is set as default. Add facing control as an option. Usually, my facing is fine. Mob tactics are terrible. They should flank and use altitude.
The copyright infringement is pretty severe. At least put in the effort to rename the things you steal, then you have a chance of claiming artistic license. Copy/paste is simply laziness.
