This game has the potential to be one of the better ones in the play store but is held back by incredibly unfair buffs and AI. Buffs at the master level and medal requirements can make some nodes frustratingly impossible, In particular, overly strict medal/character requirements, are just plain rediculous. the time requirement for matches is overly strict. Too many buffs are capable of unfairly stalling and the AI cheats or lays out perfect combos leaving a player with no way of winning
