Overview
Project Nepenthes is a 3D tentacle simulator for players who want a focused, visual-first adult toy rather than a long campaign. The tone is glossy and mechanical, built around a small repeatable loop instead of a story.
Gameplay
The core loop has the player extract mana with tentacles, using the resource to unlock new tentacle types and customize the female protagonist. Options include lactation, impregnation, anal, and breast size, letting the player shape scenes to their preference. Progress is tracked through a simple statistics system rather than branching choices.
Features
- Shiny 3D graphics with animated tentacle-based scenes
- Character customization tied directly to gameplay unlocks rather than a separate menu
