The main character is probably Sue. In many stories, when a name is at the beginning like this in the title, it usually refers to the central figure. So in the 'sue cave story', Sue is likely the one around whom the plot revolves. She could be an explorer, a scientist, or just an ordinary person who has an extraordinary experience in the cave.
In Cave Story, if there is a monster named Sue, it could potentially have characteristics related to the overall theme of the game. The game often has monsters that are designed to be challenging for the player. So Sue might have high speed to catch the player off - guard. It could also have some form of attack, like shooting projectiles or lunging at the player with its teeth or other appendages. Also, its color or shape might be designed to blend in with the cave environment to ambush the player more effectively.
I'm not sure specifically what 'sue cave story' is about as it could be a very unique or personal story. It might be a story related to a person named Sue and a cave, perhaps an adventure she had in a cave, or it could be a fictional tale created for some specific purpose.
Sue's age isn't specified clearly in Cave Story. Maybe she's around 10 or 12, but it's not definite.
Since I'm not sure about the exact Sue monster in Cave Story, but generally in the game, you might need to use your weapons effectively. If it has a pattern of movement, learn it and dodge its attacks while shooting at it.

I'm not sure who the main character is in this 'tiny man cave story'. It could be a regular guy who just wanted a place of his own.

Since the title mentions 'mr little', I would assume Mr. Little is the main character.
Given the name 'little man cave story', it's probable that the main character is this 'little man'. He could be a child, or maybe just a small - statured man. It's also possible that the 'little man' is not so much about physical size but more about his social standing or his self - perception, like he might see himself as unimportant or overlooked in the world outside the cave, but within the cave, he is the king of his own little domain.
Since the title mentions'man in a cave', the main character is likely that man. However, without more specific information about this particular story, it's hard to say much more about him.

Since I don't know the story, I can't say for sure. But generally, a'mom cave' might be a special place for Sue's mom, like a private space where she can relax or do things she likes.
