Fighting the Succubi in the forest put the fear of god into me. I have like 8 different save files from save scumming to figure out what to do on NORMAL. It feels like I'm playing a friggin' Shin Megami Tensei game....I kinda like that, but damn. Just having a few more Calm Nuts would help, even if you have to buy them because you're pretty much an easy target to get temptation looped until you get defeated and reset, which I didn't realize also gave you like 2 different moves to actually fight back the first time it happens. It would have been nice to have those from the get go so I wouldn't HAVE to lose, ya know? And fuck me, those quick time events don't play around, I can't even look at the timer, I just have to do it and hope I don't hesitate. This is surprisingly ruthless for a newcomer.
Anyway here are some quick tips for anyone struggling with the demo.
1. You can't lose the first battle with the blonde, it's just a tutorial so just keep attack with kiss then HEAD THE FUCK BACK to the fairy to heal. You can heal your vigor with healing items but you can only heal your stamina used for special moves through the fairies, so don't bother using healing items unless you have high stamina but low vigor and you don't think you can outrun a succubus.
2. Don't bother using the hand commands, neither the lip touch or the ass grope commands. None of the succubi have an ass weakness, and lip touch is strictly worse Kiss.
3. Try to grind to at least lvl 3 off of pink succubi before facing the Lamia in the area above the main forest, you will likely lose simply due to the lack of ways to reset lust and be fucked to submission. Don't worry, you'll reset in the chicken's house and get Thrust and Thrust! which will let you do incredible damage in exchange for draining your stamina really quickly. Thrust! easily does 200+ and 500+ on a crit(yes there are crits in this game), but is functionally a one use ability do to using 60 Stamina. Thrust is 30 and does a consistent 150+ and you can reasonably work around that. My strat is to use Kiss as the main attack, hope to get succubi stimulated to take more damage from every attack, and once their low enough, try to end them with Thrust!
4. Buy new armor when you can. There is a lion that sells three ranks of armor in the main town, don't bother buying the +1. Buy the +2, equip it, grind money until you get 400, then buy the +3. You need every stat buff you can get.
5. There are accessories you can equip to change certain things. DO NOT EQUIP THE BREAST ACCESSORY. I'm 90% sure it makes you take more damage from breast attacks which succubi love to use and if you really want to play just for sex you can get the same effect by just having high lust and waiting on turns/surrendering. Instead, equip the one that gives a 2% boost to...something. I'm not sure what exactly, but I'm 75% sure it allowed me to do more damage every attack OR made stimulating succubi easier.
6. Horde your nuts. Don't waste them, this game has no way to get more thus far. Lose to the succubi first before you even think of lowing your lust, besides you need to lose at least once before getting Thrust and Thrust! as well as I think Surrender.
