Thanks for your feedback !!
I agree the game is quite RNG... But I want the game quite hard~
And to be honest, I playtest my game myself and I don't think it's very difficulty.. It's probably because I know every weakness or where gear are. (I'll probably think about add few more gear in shop later on)
I agree the battle have to finish fast very often, But it's about if you stay too longer in battle with them, they become too strong and will defeat you.. so it's intentionnal if you get too much drain, you'll lose. (I know sometime it can be a bit tricky)
About the double growth (ass+breast) It's a spoiler but it was plan for the final boss and the special boss(with the four elemental rings)
Again thanks for the feedback, sorry for answering here later.
