Can i ask what's the stats bar on the top left ?
White is energy ?
Red is health ?
Idk about green and blue
IIRC
White is energy. While awake, it's regular energy, which means you may pass pass out if it goes to 0, and it's refiled by coffee, resting and alike; but in the dream it works in "reverse", which means you you usually begins with 0, but over time you get more and more rested and closer to awaking and ending the dream, and the things you do to stay awake outside the dream will bring you closer to waking up in the dream. The medkit also makes you have more time in the dreams.
Red is health. You lose it through hurting yourself, starving and alike. You can refill it through "healthy life", meals, medkits, some potions and so on.
Green and blue i'm also not entirely sure on how it works. But...
Blue is "mind", your cognitive functions. You get it higher through clearing your mind with a shower (specially a cold one), some coffee, "healthy life", and other things I don't understand much. You get it lower through some dangerous actions, taking "drugs", and some dialogue options, specially submissive/slutty ones and also the ones in which you "accept the changes".
Green is "will", willpower, which I'd also call "mood". You get it higher through "healthy life", also showers, some drugs, coffee with milk, showers, and so on, and you lose it through bad things happening and, mainly, on dialogue options, specially the ones in which you talk about lore/relationships/advancing the story with the girls, and also other dialogue options that I don't understood it properly (based on the catgirl job, "acting different but no so much?").
At least that's what I was able to understand. I bet I could know more things if I played like a regular person instead of trying to do most things in a "prude way" first, but I hope my "almost virgin" route knowledge was able to help in something.
I haven't heard the rest of the guide yet, but I searched for "staff" and this was the only place this word appeared.
Well...
I got it and I expected I would simply start throwing magic around, maybe use the axe or a knife along with it and become a battle mage, defeat hundreds of slimes and other monsters in some minutes with cool combos, bathe in their blood as a revenge for all the people they hurt, for all the people they raped... And I remembered this kind of thing is actually from another game.
Shit... This is the third time of four that I got the wrong thoughts. The first was when I found the knife, the second was with the rifle, and the fourth will be when I get my hands on the axe.
Anyway, I still don't know how to use the staff.
