I really enjoyed this game, concept is best I have seen so fart in VS genre, my problem is the more You play, more bullethell mechanic is lost, after while there is no need for dodging, monsters die anyway and that have no real impact on game.
Also different kind of monsters should provide different souls, now only viable tactics is just spamming lower tier mobs to get highest souls count and then just kill hero next wave.
It has ALOT of potential.
