Gameplay: TEDIOUS. The grind is absolutely horrendous. It started off okay, but beyond the first... "region"? it just went downhill. About 3/5ths of the way through the game, I ended up resorting to a save editor just to make the slog more bearable, and even that only helped somewhat. Enemies are WAY too populated on most maps, and a lot of them are either unavoidable or chase you down at ridiculous speed. Some enemies just plain have unfair and ridiculously OP abilities later on that ultimately mean you can just randomly be in a no-win situation no matter what you do. And there are some.... "puzzles" (and use that extremely loosely here) are beyond absurd. Basically having to navigate totally blind through the walls in some areas with no clue at all what direction your supposed to go. I could go on and on, but suffice to say, while the idea of this game has some things going for it, the result is infuriating and mind-numbingly boring.
Aesthetics: Overworld is bog-standard RPGMaker resources, though the battler art is nice enough. Cute chibi style that's reasonably well animated. Music would be nice if you didn't end up hearing each track endlessly looped for so long you go from loving it to hating it due to how long you'll spend in each area. Oh, but is it LOUD. Even with my computer's volume turned down to 10, I had to turn all the game's internal volume settings way down for it not to be absurd. So keep that in mind before you load this thing up- IF you do, that is- and mute your pc before you have a chance to tweak the settings.
Content (General): The game is LONG, but that is largely padded out by grindtastic annoyance-fests. There are a reasonably wide variety of enemies- at least 30- though some in the late stages are reskins of the same design, including the same animations and usually even the same weaknesses.
Content (XXX): This is probably the game's one redeeming factor. The "sex battle" mechanics here are nice, if imperfect. Beyond item use, escape, and some more utility-type skills you pick up throughout the game, most of your attacks fall under three categories: Hand attacks, Tongue/Mouth attacks, and Penis attacks, the latter of which is unlocked only after making the opponent horny enough via other means. With each of these you can target the opponent's breasts, pussy, mouth (though not with hand attacks, interestingly), and ass (mistakenly labelled hips in the game). Each enemy has a weakness which causes them to be "damaged" as well as increase their arousal bar further. In addition to these mechanical features, they all have different animations. Additionally, the enemies have matching "dominate" counter-animations for these acts.
Other: One bug I encountered was that on a certain map, everything would sometimes slow down real bad. Supposedly this is because of the lighting effects, which you can disable in the menu; unfortunately, in my case at least, doing so did nothing to solve the problem after it started, so it usually resulted in me having to save and reload to fix it. Mildly inconvenient, but luckily it didn't happen super often.
Overall: If it wasn't for the porn aspect, I'd give this one star. It's that monotonous. So tedious and irritating that it actually ruins what would otherwise be a fun sex battle mechanic. I absolutely do not recommend playing this game, but the animations are nice. So either get a 100% save from someone or just view the videos that are easily accessible in the game's resource directory under "movies".
