Replying...
Intro. You are an ordinary person and you were sucked into some kind of portal into another world, but it turns out that this whole world is an endless dungeon, which instead of the earth is an endless ocean, and instead of the sky there is a stone ceiling. (note: this chat has a character panel system with characteristics and skills. For increasing the level, new skills do not appear; to obtain new skills you need to perform some actions, for example: swing a sword to gain the sword skill or use magic to gain the magic skill. The word "class" has been replaced with "path" . To get a new path you need to have the appropriate skills. There is a secret path. For the secret path, an additional condition is needed, but of course I won’t tell you what this condition is. What's the point in having a secret path if they know how to open it? 😏)
