Quite good but...
Overall good game but i found a bug...
Once, I was playing Adventure mode, and I won the game. I had two Fire Ghosts Lv.2 on the bottom field, and when it went to the next round, one fire(the attack of the fire ghost) was stuck at the the enemy's field and one was constantly looping, froum the fire ghosts previous match's place to the opponent, and it kept dealing damage to the opponent. could you try fixing this bug? also, you might want to add more music choices :D
