This is an okay game at best, I'll be the first to admit that For a game that is based on Lust and Desire and Corruption... It really really fails at the corruption part. 
Expect your typical Magical girl meets enemy queen that easily corrupts and transforms the magical girl into her 2nd in command type stuff because the corruption that happens in this game is just sadly that fast and loose. 
Typical Fire Emblem Combat 
Decent Music
Good Character designs with does have a Base of A.I in it 
But in all honestly don't let that really be a factor to make you change your mind on this game. There is a difference in, using A.I to aid someone who may not be skilled in Art make their own original characters, and someone who uses A.I to justify stealing someone elses characters. 

It needs work and honestly a story revamp if it really wants to sell the whole corruption bit but i say its a game worth giving a try
