This game is a sequel to Last Embryo, with same and new character cast, gameplay, world and a continuation of said story, with decent, just like it's predecessor, gameplay - but let's get on things that well, I have problems...with.
The translation, the main point of such games is...just like its prequel, just...better than machine wording, but with A LOT of misspellings, like angle instead of angel, broken English, certain untranslated Japanese and other things that make it yet another case of bad proofreading - I am not surprised why people complain about it, because when people do bad faith to such works...it makes it worse, unless it was already bad to begin with, in which case, its barely an good or bad thing, but an amplifier to it.
The story, just like its prequel, is a case of "but you are not a good guy expect you still are in the end as long you succeed", and "oh, you beat a boss to a certain line, let them shoot an super attack" instead of you know, continuing the fight like a proper prepared person, you get interrupted by secret backups and sudden awakenings - which last even longer, and detract from gameplay, in my opinion.
Now for actual story that this game has, which I'll have to warn about having spoilers, well, you play as a magician, who continues their venture from the prequel game, while knowing the events done by its protagonist - and after doing various stuff, like somehow losing to force of heaven and getting cursed with lust, then overpowering yourself through desperation, and defeating the holy evil - almost at cost of your life, just like the previous game protagonist. And just like losing all hope, it suddenly gets back - basically bittersweet moment that instantly turns into hope because we can't kill off an important character yet. Overall, fairly average, but it could be worse like other cookie cutter RPGs that are pure nightmare or boredom to play.
Now for gameplay, which is similar to the prequel, but instead of animated sprite doing the combat, and generating TP before unleashing your power attacks, you unleash spells instead - basically just get high enough level, upgrade your spells enough, get the best equipment, and you are set for the entire experience - which I thought of more than just that. Overall, the gameplay is average...just like its predecessor, expect you have the TP bar replaced with lust, which makes you want to kill enemies as quickly as possible before you'll be stunned for several turns - and they already die quickly enough before that one becomes prevalent...unless you lose too much, or fighting a boss.
Also, there's one minigame, that is in prologue ship area, where if you do not go to the deck yet, you can find a chest, that triggers a lockpicking minigame - and only 1 in the entire game, which makes its presence rather disappointing, because features that can make the game good if done properly should have a good enough presence before being forgotten almost instantly.
The sexual element, which is something I usually point out but never rate because I judge the general quality rather than that unless it has a heavy impact/main point of the product, well, is scarce and mixed with all kinds of desires, from bestiality(which is gross, in my view), lesbianism, and others - fairly decent amount of interests overall, nothing too abnormal, aside from creature intercourse and growing parts. But encountering them during normal path makes them fairly scarce, and even if you do get into it otherwise, its still fairly small amount of.
So...how this game fares overall? I'd say...fairly decent, but nothing much - just pretty stuff, a story that makes sense but falls into too many average anime tropes and could be better, gameplay that is fairly average...basically only thing that is really good is art, but whenever it has problems with proportions and such is...up to debate. Neither bad, neither good - I have seen games that do their supposed job much better, while also not being bad enough, which I am thankful it's not - the worse the bad element is, like a improper or not good enough translation, the worse the product overall - I would say, I felt nothing after completing it, however, the price tag of 15$ for what amounts to about 3-4 hour(maybe 5-6 if you try to get the alternate ending after knowing the normal story)experience like its predecessor, I do not think its good enough to justify the price for a fairly average experience. Pretty but not good.
Edit: So I tried to get the supposed alternate "bad" ending, and oh boy, the prerequisites are so ambiguous with intentionally losing to pre-placed traps to even get to that point, not helped by fact you have to do those repetitive acts like for eternity(increase/decrease in stats in final zone didn't help either)until you can even get onto that path - meaning it takes more effort to get that special scene than to complete the game!
The game states that all characters are 18+ of age, but the actual situation tells otherwise - there's a midget martial artist, who's referred as a child by bystanders when you try to free her off the box, and a underage boy, who you can offer sexual favors with...after you get cursed that is. Pretty bad excuse when you have scenes like that, isn't it? Not to people who's here for sex of course, but to hypocritical statements that everyone's adult here but still have childlike characters - which really kills the statement in the first place.
As for game itself, just like I said before, it hits between average to bad, which due to fact there words speak better than the rating itself, I'd say - average trope hitting story that cannot be taken really seriously, or funny for that point(but not bad), average gameplay that brings nothing new to the table(but not bad either), sexual elements being fairly uncommon(even if you try, they are unsatisfying), generic music(but not bad at very least), translation is enough to understand stuff(but very sloppy to be called professional for money), short and overpriced(now that's a bad point). If I only had a choice between yes or no, I would say no for sure, after all considerations.
