Oh I remember this game I still have it, wanted to revisit but got instant memories of it after 30 min...
The constant "oh god a demon I have a boner" is tiring very fast or the amount of stupidity put into this MC made me stop, I did it once before just revisit the collection room.
This game is a disappointment could have been better, I don't understand why you would build characters(referring to the sisters specifically not the MC) to just make them how they are over time by bluntly saying demon = horny "it's ok it enters in the stereotype square".
A lot of parts in the game are confusing and I wonder if different people worked on it because sometimes I got the feeling there was a plot route against the MC and there will be a "Bad End MC" CG but no, making the sisters a bit more serious sometimes and shortly after making them stupid.
I know "it's just a porn game" but to me it's not a good enough reason to neglect parts of it, I do play/look at porn games that are totally made to just jerk off but when you start putting a whole backstory make it right all along.
What I liked the most is the art I really like the attention to details, that the sisters have different looks and bodies, with pregnancy it's even more noticeable, that's something I like to see since I haven't witnessed that many games like this.(there's probably others but I don't have that much time to dig deeper, what I found the most on the surface are "copy/paste" bodies and that's all) liked the voice acting too always nice to have it.
If it was a ADV/simple visual novel with L2D/animated scenes it would be better, the very basic RPG makes it worse, having to lose to evolve is sleeper most of the time.
Plus not enough CG even if it rotates around the MC, nothing with other demons and with all the differents sprites there was enough material or just between the sisters since at some point they end up being slutty demons anyway.
Would totally play a game with sisters like this(how they were at first), without a MC like this or please give a full route to plot against from the start, I know the title go against that but I remember playing porn games that have the main story and routes that go against the title, it's then just said these are non canon route.
Or re-using these sisters in a different setting(change story) and maybe an actual real RPG, with skills or talent trees since it's said that for example Lyla have magic enhancing her body strenght.
Ok to play once but then just recollection room.
Truly a shame to have art and VA like this put inside a basic RPGM game.
