is there some list that tells which commands each girl is weak and resistant against?
Though dialogue might imply otherwise sometimes, there aren't really weak/resistant "elements". The difference is more in how you "fight".
i see a menu with 3 optiions the first seems to make you cum "is this a request to enemy to make you ejaculate?" the 2nd reduce your life to 0 "is there a goal in mind to use this in battle? like trophy or secret that you get when you lose by this way many times?" and the 3rd option that makes both you and enemy meter go to max and after player cum a few times , the battle is over. does something diffrent happen when you pick this 3rd option later in a battle rather than at the start?
Those three options should only appear in the Time-Frozen Basement aka, the memory room. They're just a quick way to see the related scenes, or to just end a battle quickly. There are trophies for doing set numbers of "battles" in that area, but none for picking those particular options.
is there consumable item that boost enemy mood?
Not directly, that I recall offhand. There are a few Aromasphere items that will buff how much your actions increase mood for a few turns, though.
what icons/text represent each mood?
as i can not tell which mood i am in at any given time in battle.
In general, orange icons/commands reflect the Resist stance, Purple indicates Fear, and Green indicates Obedience (and pink, which are rare and generally story based, indicate Love). You can also check your stance gauge in the bottom right. Even in the English translation, this uses kanji, so it's not perfectly understandable, but the colors are still present, and for what it's worth, 抗 is Resist, 怯 is Fear, 従 is Obedience, and 愛 is Love. The Succubi stance gauges vary depending on the opponent; in general, 搾 or 虐 means a big attack or damaging effect, 捕 is usually a status effect that will restrict your actions, and 弄 or 遊 are a bit more variable, but usually status effects. That's just in general, though, because each enemy is unique.
is bored mood when you can not do anything?
No. Bored is sort of a "shield" that keeps you from increasing mood until you break it down, and every few turns you'll get hit by an extremely powerful attack. It has a random chance to happen when you "miss" with an action, and you'll see 飽 on the enemy stance gauge. There are a few statuses that prevent you from taking any normal action (as well as some that force you into certain stances) but those don't have much to do with boredom (mostly...one Notorious combine boredom with status effects as part of her gimmick).
is there a english list or guide that explains these things and shows what each thing does and shows the name of them next to their japanese text seen in game?
Well, the official English patch is still under construction, but the unofficial one is available
earlier in this thread which has all the non-graphical text for the game's original release translated.
as i try playing around with the game and experimenting despite not knowing japanese and im unable to tell if there is some kind of rng to the battles and how high the enemy meter has to be to trigger the naked costume change.
There's some RNG to it, yes, like most RPGs. Generally costume changes will start having a chance to happen around 50% mood.
there is item to heal the life meter that goes down when player cums?
Yes, though they're somewhat rare, especially in the early parts of the game.
as would like to see if possible to make a battle last as long as possible to trigger change in enemy costume and what defeat looks like in their changed costume.
1.2 has a "lock" button that will cause a battle to continue endlessly once an enemy hits 100% mood, until you die or turn the lock back off. The official English patch will include that, but the unofficial one is on 1.0 though. Unlike most game updates, I
may be able to do a quickfix for that. I will do a couple tests and see, and if so, upload it if possible.
this battle fuck game have system where enemy can deal critical hits , and is the text diffrent when enemy land critical hit?
Critical hits exists (called "Luxurious" in this game), and the Obedience stance, especially, is sort of built around them. The flavor text does not change for them, though.
does enemy damage go up when mood is higher or lower?
Enemy damage does not scale either way with Mood, though for certain specific enemies, hitting certain Mood thresholds might unlock the occasional new strategy.
like sometimes i see player life go dowm more than 30% opon cumming.
when ep meter is higher than the cap "like when enemy does over 3000 damage in ep or something like that when your ep is lower than 3000" does that mean the higer this number is over your acutal ep the higher damage to life is?
Yes, the higher your EP goes past your limit, the more life you will lose. There's one boss in particular that can basically one-shot you (no pun intended...) on higher difficulties that way, and one of the Notorious also exploits that mechanic in both her confrontations.
