The rotating board def reminded me of YuGi-Oh! I like the cards and their illustrations. The overall controls were a bit confusing at first, but I quickly got used to them - if I were to give any feedback maybe mouse controls would help with this kind of game.
The combat animation and overall mood of the game are good, and I like the variety. I think the board could be smaller so it wouldn't be as intimidating at first, but when you get the hang of the game, it all makes sense. It is definitely interesting to see a card / board game in 64x64.
Is there any way to unlock the other board? I couldn't seem to figure it out hehe.
Overall, pretty interesting experience! Good job!
