About Side Effect
Side Effect is an adult text-based visual novel by Guma Games, built with HTML and Twine. You play a 44-year-old writer and former literature teacher who now shares ownership and management of Riverton High School. The story is set in Riverton, a lively but small city, and follows a man coming out of an eight-year depression after taking an experimental medication. It focuses on introducing characters, forming relationships, and branching paths, with adult themes including cheating and interracial relationships.
The current release is Chapter 1 Part 2 v0.1, dated December 10, 2024, for Windows and Linux in English, uncensored. Development is ongoing, though this update concludes Chapter 1. It adds a character stats system with Patreon premium cheats, lets players choose main character names and step-girl relationships, includes eleven new scenes between days one and six, and provides premium Patreon scenes with Leah, Danni, Skye/Valentina, and Katarina. Several scenes were rewritten, image bugs were fixed, music was temporarily removed, and the chapter ending was added.
Developer's description
Side Effect is a visual novel-style game, developed in Twine, which aims to deliver a story rich in detail and with several options for paths to follow. At first, the focus of the project will be on introducing the main characters and building the basic relationships between them and their possible conflicts. In this story you will play a complex man, a writer and former literature teacher who now co-owns and administers the prestigious Riverton High School. In Riverton, a vibrant yet quaint city, you, at 44 years old, are emerging from the shadows of a debilitating eight-year depression. Thanks to a groundbreaking experimental medication, you find yourself reinvigorated, ready to reclaim the life that once slipped through your fingers. From a shadow of your former self, you are now filled with a newfound zest for life—and an unexpected side effect: an insatiable desire that seems to have awakened after years of dormancy. Spoiler: More details The project has only just begun. I'm not a programmer, English isn't my first language and I'm not a visual artist. Therefore, the structure of the game will be very simple right now and I will dedicate my time to making the game mechanics more interesting as the project progresses. I want the game to be collaborative with those who believe in and want to support my work. You can contribute to the project in various ways. You can support me financially through the platforms indicated in this post, but if you don't have this condition there's no problem, you can give your opinion, suggestions and constructive criticism so that I can deliver a better job. Thank you in advance and I hope you enjoy the game.
