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.

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.

Good: - high quality media - decent choice of girls - UI isn't bad on the eyes Bad: - More of a Kinetic Novel, choices don't have consequences besides the one in the beginning. - Broken on some browsers due to mixed casing on media. - People are... very chatty. Ugly: - Basically an "instant fuck" game. There's no rhyme or reason, just each woman you meet you seem to be able to instantly fuck. - Due to above, it's a mile wide and an inch deep.

Side Effect is one of the few HTML games with a neat, appealing user interface aka GUI design. The text-based tag is kind of misleading as it has plenty of adult/porn video content which is properly sized, formated and embedded into the GUI. There are also pictures being used - some video stills, some AI generated. It's all about the MC who returns to his family and work environment (school) after an extended sick leave due to mental issues. Hence the game is populated with wifes, sisters-in-law, daughters, nieces, colleagues / co-workers, students and business partners. It is not an open world game where you have freedom to choose your daily activities and hope to find the right trigger, but a visual novel with limited choices. Since it's the 2nd release so far, it is too early to decide whether it's going to be a kinetic novel or feature distinct paths. There is plenty of sex taking place already and I would say we have about 1.5-2 hours gameplay now if you actually read and follow the story. I recommend to give it a try.

A very Rare example of good html game with hot LI's and coherent pacing but would be great if had sound and some more save slots and also a gallery option. also the character relation page needs some clarity would be a 10 times better if it was harem but this is my personal opinion 8/10 good game
