A huge downgrade from the original game,it offers nothing new and improve save for bugs and somehow worse mechanics and everything is noticably slower and more chaotic,honestly this game shouldn't just be a carbon copy of the original,the dev was mistaken to do this,should have made this game unique on its own and learned something from the last,cant recomend it unlike the original.
This game is pretty similar to Jumble Strikers (and the previous game, Amadeus, in the Kurenkisho Quolta series), but it compares quite unfavourably to that one. For one, in Emeraude, regardless of whether you have the lewd status effects and body changes or not, combat is quite slow. It is common to get restrained by an enemy and have to endure 10-15 hits before breaking the restrain. It's ridiculous and a huge time-waster.
The story is really generic. Succubus captures people and tortures them with pleasure. Why? Why not, I guess... And our heroes, or really just Emeraude since everyone else is defeated by Misty and her friends and are used as obstacles to Emeraude instead, has to go through hordes of goons and too-large maps to beat some bosses before the game ends and sends you to basically a debug map where you can fight any monster you want.
As for the porn...well, the art is fine. Not great, but not bad. But seeing Emeraude enduring lewd attacks...just isn't hot. I had this problem with the developers last game too. I think part of it is the slow combat, the art not quite being good enough, and lack of variation in facial expression, and climax not feeling impactful enough. It would have been better if, like in Karryn's Prison, Emeraude could engage more with the sex battles instead of just standing around while others touch her. Currently you play for 3-4 hours and it just feels like a waste of time.
