The Proteus Effect is a lighthearted roleplaying adventure game where you take on the role of a down-on-his-luck guy who lands the job of his dreams as a playtester at a virtual-reality game company. Things don't turn out quite as he plans, however, and he soon finds himself both trapped in the virtual world and stuck in the body of a nubile young woman.

Join the hero and his companions on their adventures through the fanasty-themed worlds as they try to figure out what's behind the game's strange malfunctions and ultimately find a way home.

The game is made with RPG Maker MV, the latest version of the RPG Maker engine, so the playstyle is similar to the old Final Fantasy games. If you've played RPG Maker games before, you'll be glad to know everything you need to play is included in the download (MV doesn't need RTP packages).

This is an adult game, of course, so it includes sexy content, and much more is on the way. So come on and play! You'll have a titillating time, you might enjoy the story, and there's an outside chance you might learn some things about yourself along the way!
