I just read your comment and the 1st thing I have to ask is: Have you read the introduction of the game?

Many of your questions have an answer in there and moreover, it is referred to that the icon below the game clock (the one with the book) is a grouping of the game's explanations ( Still under development because I need to add more information).
- Strengh, why increase it? No need to do it to the max but it can help people who are struggling at the beginning of the game.
- The cost of making potions is too expensive? Several skills can fix this, such as the mechanic that decreases the number of droplets. Another increases the amount that monsters give at the end of the fight, ...
- Problem in the cave with fight monsters?
a. You can run away from a fight after it has started.
b. You can buy magic items from the cave vending machine. There is a teleportation item to leave the cave in an emergency and others that can give advantages. You can buy equipment too.
c. There is a pharmacy in town, there may be potions to cure yourself.
d. There are also other ways to heal yourself such as food and spells to unlock.
PS: The random monster encounters are the basic option of RPGmaker...
- Talk / Flirt / Sex / Sex vulgarly : The 1st allows you to earn friendship points and the other 3 give Love points but according to the corruption points that the NPC has. This part is still in development and each NPC must be customized. You can still see the corruption points you need to have for each choice in "my info about her".
- The quests to unlock the content can be divided into 3 parts. Getting to know each other, seduction and intimate closeness. This was designed keeping the theme of the game "the hero is rejected by everyone until the day he is the only man left and he has a way to corrupt the women he meets"
- Intelligence? there is a school, you have to follow the courses to increase it more quickly. Homework is just to avoid the loss of intelligence.
I could tell you a lot of other things about the game but I'll let you look at the guide in the game and you can also go to the GameFaq. If there's a problem, you can ask me
PS² : The book icon for in-game explanations will be replaced with a question mark in the next version.
I feel like you didn't really read my comment. Skimmed through it, maybe saw some things other people also commented and gave a standard response.
I've read everything in the book and some stuff on the forums as well.
I didn't ask where to increase strength or int, or why to increase them. I said that it makes no sense to go to the cave without maxing them. Which maxes for an unenjoyable experience. Int later on, if you want to use spells, strength for killing faster, of course. Regarding the potions, I mentioned they are too expensive at the start. I've read all about how easy they will be to craft later on. But at the start, even with maxxed mechanics and alchemy bench, they are a pain. It takes the whole first area to craft like 4 potions. (if they cost 25 each). They game accelerates faster and faster, if you increase drop rate, get to higher mobs, I get that but I think you haven't really played your game at the start, you play the late stages and it feels more than fine (more on this later).
I found the item for teleporting to the start later on, it is indeed very useful, as I mentioned, it was what I had found in my first hour and a half. I know you can run away from a fight, but it has a success chance. If you realize you are in trouble and low hp, how many encounters do you think you can run from until you get screwed and die. Will look into potions, haven't checked them yet but sounds good to me.
I understand that random encounters are in RPGmaker but I've played games where the monsters are on the map and the battle only starts if you clash with them. Not sure how hard that would be to switch from the default system.
I've later discovered the more info about her and that you find out more, better than nothing, but still not ideal, will mention it all at the end in a structured way.
The idea that you have to corrupt someone before you can flirt with them is hilarious to me. I can understand having to do so maybe for family and some teachers or something but for everyone?
Now, for the structured part. I've played the game some more, throughout the day, with pauses for about 9 hours in total.
I fell like there are 2 games forced together into one. Each of them could be cool by its own, together feels like too much. There's the dungeon explorer game, where you grow, use companions, get rewards and progress. And there's the corrupt girls game, with a crazy amount of them and quests for each, that take you all over the city. Their only intersection is the fact that you are forced to increase some of your stats and the girls corruption through potions. Imagine playing a "porn game" for 9 hours and not seeing a single sexy scene. Sure, I've watched some girls and the gym or some other places but still. It's crazy towards the extreme.
Now, on to some feedback. You can of course take it or leave it, I'm just saying how these things would have made the game more pleasurable for me:
- The need for potions for every single point (except str, int and mechanics) is horrible for multiple reasons:
- You finish first few areas without being able to unlock a single chest because of the lockpicking skill. What kind of game gives you rewards you can't have for no reason. I put some potions into lockpicking (like 12) and I only opened 2 chests in like 20. That's crazy. Also, why would he not be able to learn to lockpick without a freakin potion, it's an ordinary skill, nothing magical
- The observing skill (clairvoyance or whatever) has the same problem but for different reasons. This is what increases your drop rate. It's supposed to help you out especially at the start and you need it for some spying around town. Why not have all the watch girl events increase it as well? Maybe have some caps every 10,25, 50 levels where you need a potion before you can increase it further by normal actions.
- I imagine silenced is the same, only increased through potions. I would hope you could also increase it through actions. Look at how popular Kingdom come deliverance 2 is right now and heading to game of the year. How do you increase stats there? You do the actions that needs those stats. Best feeling in the world for a game: keep doing something and you get better at it.
- Same for corruption. I would love for the potions to be an added tool or for some special character, but the character should be able to corrupt at least in part with some actions on his own. I would have even preferred if the potions increased his power of corruption, and then he could corrupt girls up to a certain level, depending how high his stat is. The way it is right now, how many potions do you need to complete all the girls? How many thousands, if not more.
The interface for the girl info is horrible to navigate. Yes, the phone makes it a little easier to access but it's still bad and painful, especially if you need to see any girl after the first page. I know you have a dosier to follow certain girl and have them on "first page" but that isn't helpful enough. I had to make a document with all the girls next quest so that I don't have to go into that interface all the time. Especially if you want to optimize and do multiple quests at the same time.
Here comes the part where you have more information about the girls. Yes, you might know, if you are friends at what levels you can do what. But there are a lot of girls in the game, if you don't remember them all, it means you have to constantly check in the painfully tedious menu to see if you can do a certain action. Having it updated (if that's possible) in the direct menu, once you have the info would be so much better.
I am just going to mention this, doesn't bother me too much in game but it's an example of grindy/annoying for no real reason. Loosing int if you don't study/do homework for 3 days. Really? Is our MC that stupid or do you think that's how it work in real life, if you don't read for 3 days, you become stupider. And by a very big percentage I might add. I mean, really, what real purpose does this serve in the game? For who is it put in there? And why is it not the same for strength if it's just for annoyance sake. You loose strength if you don't work out a lot faster than you lose your intelligence.
The cave: The fighting is so bad for so long. I almost got to the end of the second area, I don't know if it get better later on but how many players will you lose until than (if it really does get better). All I do is keep spacebar pressed for my fights. And the fact that I have companions with me is actually slowing me down, even if I can get a little further. Yes, for some fights, it might be a little better to use aoe, and for some fight I do use the double hit if I feel like it, but those aren't really battle-changing decisions. With full strength, and the 3 pieces of defense gear, you can one shot any mob and you don't take damage from first area. This means that as gameplay what I do is walk around and press spacebar. Seriously, who do you think want to play this game. Or is this like "work" before you can get to the good stuff? Why not make all gameplay feel good?
I want to admit that I rarely like rpgm games, for the nature of the engine which makes it unnecessarily not fun but I've enjoyed a few of the good ones like Karin's Prison.
I would recommend, if you have the time, to start a new game and see how it feel. How enjoyable it is, and how long until you actually like what you are doing in the game. Maybe I'm wrong and you enjoy all of it but I think you don't really remember how it feels at the start. Better a game lasts 20 enjoyable hours than 100 miserable ones.
Just my 2 cents.
Will give it a few more hours tomorrow, just to see how the corruption goes with one or two characters and afterwards I will probably call it quits and write a review. If there was an option to not play with the cave system at all and just wander around town, increase my stats by doing actions and corrupt girls the same way instead of magic potions, I would have loved to play this until the end.
