The Soul Link is the game's new main progression. There are no more levels or skill points, only the soul link.
The soul link is a gameplay where each npc you manage to exchange energy with (most of sex scene) will add their soul to your total possible link. Each doll has a link limit, so you'll have to choose which npc and which stats to boost!
Soul link stats can be seen when you talk to any npc, their stats appear with numbers next to logos corresponding to each stats (many new stats are appearing).
Every link can be see with stats menu (TAB per default) and modified with an "Soul link Altar"
Here's a summary of what each stats does:
Vitality: The amount of life in your doll
Stamina: Your doll's stamina and running speed.
Agility: The speed at which you dodge and perform other combat and movement animations.
Strenght: The strength of your sword strokes
Resistance: How well you reduce the impact of damage on your health. (does not affect status effects)
Inteligence: Not yet implemented
Craft: Your ability to create more or less complex and useful objects.
Charisma: this adds up to what a npc thinks of dolls. This value can be nullified if the npc has a higher charisma than you. (can't negatively affect your relationship with npc)
In the future, new stats may appear. There will also be npcs that are more and more interesting to link, and species that are more specialized than others (for example, elves will have a much higher agility than humans on average). Different ways of increasing the maximum link limit will also be available, allowing you to increase your power considerably!
Specialization and the creation of several dolls will always be an advantage!
