That's a strangely wholesome lewd game.
I would not describe it as a linear text heavy story though. That would make me think of a kinetic visual novel. Instead it is a solid shortish (few hours) adventure game. You do mini quests and level up and need to find things and figure them out. It is linear in the sense that there is no story branching. But there was no story branching in the Larry games either.
The game would work even without sexual content. The plot is simple but captivating.
