Great premise, but flawed play.
I liked this game. I was playing for hours even with the flawed systems and interface. The layout it great, the cards are nice. I enjoyed the power-up system involved and the strategies that could be presented in a match. That said, here are the problems as I see them:
• No discard option. I often ended up with cards that I just used up to no effect because I had no use for them. There were also cards I was trying to avoid using, and ended up using one card out of six over and over again hoping for a discard. I doubt anybody wants to reset thier offense/defense when they have a 10 point lead over the opposition. I didn't want to use up all of my Hazumi points on a cure that I didn't need, after I racked up 84 of them just trying to see how big of a hit I could land.
• Not enough attack draws. There were matches in which I could not defeat my opponent because I could not hurt them. They were regenerating two health each turn, and I could do no damage at all, in any manner. I think the same can be said for the Hazumi cards also. Sometimes I'll end up in a increase/decrease match with my opponent without having an option to do damage or not.
• When the opponent discards, or uses a double attack card, it does not refresh your hand. It's also troublesome to know when you can go again, or if the computer is still choosing, because the cards they use in this process do not get removed from thier hand immediately.
• I found myself never using the poison cards. It seemed every opportunity I tried them out, the computer used the card that turns it into bleeding damage on me. For all the times I ended up bleeding, I could hardly ever find a cure. For every "poison to bleed" card I saved, I never got hit with poison.
• The one-turn effects are virtually pointless to use. They always work against the player also. Timers cycle after a card has played, before the effect. If I reduce the opposition's defense to 0 from 6, it doesn't last long enough for me to attack on my next turn. This makes the card dependent on the double attack one.
• When the other player uses the "see opponent's hand" on you, you can see thier cards. Just a wierd thing to do.
• When using multiple cards, it's slow to react. I'm not sure when I can use the next card or not. A text message notifying you when it's your turn would be helpful here.
• Spelling errors, simple ones. Strenght, Taclke, Typhon (Typhoon); another minor error that could improve.
