Very good
I played this for about an hour thirty and eventually I got over 10000 hp and all of my magic attacks and standard attacks did 9999 damage without a power up. From that point it just gets easy. Since none of the enemies really pose a threat it just gets a little boring to continue creaming them.
I also don't see why people should complain about healing and attacking in the same turn. It sucks at the beginning but once you get really strong you WANT them to heal themselves because it gets too easy.
Another reviewer said to add bosses and I agree with that. Fighting games almost always have bosses in them it's a classic way of constructing a game. Even though I'm just complaining right now I really liked playing this. One thing though. Can you bring the damage level above 9999?
I know most RPG's did this but this is your game! Being one reviewer of many, I don't expect much but I have the power to leave a little review at least. Oh, and more enemies in combat would be a nice touch too. I don't expect it to be simple of course. It's all about the public saying you should pay attention to.
