A bug I've noticed with the AI is how it behaves against void mage card. In some matches I win simply by having him alone in play and (probably) the opponent waiting to cast a card with mana>50. As that moment never arrived due to Void Mage, the opponent doesn't do anything when it enters play.
Cool game with good gameplay, that kept me entertained for some time.
My recommendations would go to improve car-car interaction. It's frustrating to try to make a corner and an opponent from behind flip you to the other way without much impact on the opponent.
About the PvP, I think it has much potential, but it may not be being used at full potential as players may not be willing to pay the 2.5k coins, and having the possibility to play someone with a lvl 5 times higher. It's not worth the 2.5k and make players avoid it.
About the story, I understand there should be one, but in such small letters in a small box, it takes no willing to read it at all. Would it be possible to there be an option where it would be possible to read in bigger letters and in a bigger window?
In overall I like the game. It allows to use some strategy, but only when a player has like 50 cards. I'd enjoy there to be a deck limit or more "game building" so better decks not to be just having more cards in the lower levels.
About the quest mode, it may be hard for players to fighter over and over again the same opponent. It's like, it takes 1 full day to clear a set of monsters, no matter how weak they. I usually think of quests as a funny way of progressing through the story of the game. If at least the enemies could grow in power and use different winning strategies, it would help a lot.
I don't know if it was writen here but here it goes.
- I can't buy a new deck "space" (200 coins), while I've 210 coins.
- Also I can't have my Dregasus (def=28) as my starting creature, choosing instead the Leonarth(def=26).
