The Proteus Effect v10.3 by Proxxie, 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 fantasy-themed worlds as they try to figure out what’s behind the game’s strange malfunctions and ultimately find a way back home.
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!

the-proteus-effectThis is one of the better games to be found on here. It's funny, it's well-scripted, and the plot pacing is just right. The combat is light but the renders are clever and cute and of course, plenty of sexy time to be had (do read the tags for the kind of content within, though). It also seems to be updated regularly, which is a bonus. Two hours into the game and I was having enough fun that I had to go and sign-up for Proxxie's Patreon to show support. It's that good.
