Oh man, this game was ROUGH the first time I played it. I chose not to look into any of the guides, and just started playing in the way I usually do when I'm unsure about the mechanics of a turn-based RPG; I played a generalist, with a focus on dealing damage over buffing or defensive play. I spread my edict points evenly across the various attack types, I took full advantage of the rock-paper-scissors system, I tried to use pretty much all the mechanics I had at my disposal that fit my play style, and I tried my best to keep Karryn a virgin, and not to let her slut level get too high.Initially, i played this game with focusing more on the combat (which i had assumed to be the core of the gameplay, which has been the case for most japanese RPGM games) and i found the pursuit of the purity ending (i.e. Holy Empress in this game) to be unforgivingly hard. I followed some vague guides from this forum here to achieve said ending, and a handful of commenters advised that "speedrunning" the game is most optimal for the ending. It might just be me who sucks, but i still struggle a lot with this approach, to the eventual dismay of my interest.
Unfortunately, the game doesn't exactly make it super clear that you are AGGRESSIVELY level capped in each area, and if you focus on more than two attack types, you're going to be extremely underleveled, especially in the later areas, and fights were taking so long by floor 3 that I was regularly having to wait for level 1 to riot so I could grind levels, and beeline it for the boss fights in each area while running from fights to get to the security rooms so I didn't drive Karryn's slut level way up just from the fights taking a long time; potentially even resulting in losing basic fights and/or getting her fucked.
Eventually I did figure out better ways to play the game, and got (somewhat) better at it, but it does still go to show that if you're not familiar with all the little quirks of the game (especially the ones the game isn't super up-front about, like the level-capping), it's very, VERY easy to make the game extremely unbalanced for yourself. Not to say it isn't fun, just that it can feel very unfair on either your first few attempts or when you're trying to play a specific way that doesn't really mesh with what the game wants from you.
The porn is really good though, full marks on that front, especially the side-jobs for the bar and reception. There's a good reason so many people want more of them.
