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.

There are 3 main characters you can play with. They all have their own unique stories and unique worlds.

You play as Amy, an elf maid. Deepen your relationship with the villagers, fight monsters on your way and pay a sexual price for losing to them.
