About The Sibling Experiment

FREE TO PLAY VISUAL NOVEL - 2017

Synopsis

Even though their personalities vastly differ, Jasmine and TJ share the same sentiment: their brother is insufferable.

So when a cryptic ad pops up on their computer screens guaranteeing to switch their siblings with other people, Jasmine and TJ promptly sign up—only to find themselves waking up in total different lives one day!

How will they cope with their little dilemmas? What will they uncover about their siblings and themselves in this wild ride of upside down reality? Can they ever reverse the experiment and solve the mystery behind this life-changing experience (pun intended), and at what costs?

Features

- A 82k words script with a lot of sass from Jazz and cool kid vibes from TJ.

- 8 endings to obtain.

- Custom sprites & CGs.

- Steam achievements.

Игра "The Sibling Experiment" оставила после себя смешанные чувства. С одной стороны, любопытная концепция, разворачивающаяся вокруг сложных взаимоотношений между братьями и сестрами, притягивает. Атмосфера напряженности и тайн умело создана, заставляя игрока гадать о мотивах персонажей и скрытых обидах. Графика и звуковое сопровождение вполне достойного уровня, помогая погрузиться в мир игры. Однако, сюжет кажется немного затянутым и перегруженным деталями, которые не всегда способствуют продвижению основной истории. Персонажи, несмотря на заявленную глубину, порой кажутся картонными, а их поступки – нелогичными. Игровой процесс сводится в основном к диалогам и исследованию локаций, что может быстро наскучить любителям динамичных игр. В целом, "The Sibling Experiment" – игра на любителя. Если вы ищете неспешную, атмосферную историю с психологическим подтекстом, то она может вас заинтересовать. Но если вам важен динамичный геймплей и четко выстроенный сюжет, то, возможно, стоит поискать что-то другое.

An otome romance comedy game with two female main characters to choose from. In the game the two characters basically switch lives magically with each other, so they live with the other girl´s brother and this opens a romantic story. Pros: - The game is an easy-going, light comedy for girls, if you are into that - The background art is very nice. - There are some music pieces that are really good throughout the game. Cons: Achievements are really broken, so don´t play it for that The brother/sister dynamics in combination with the rom-com style are sometimes really strange. I can only guess that the creator does not have a sibling of the opposite sex Overall it is a nice little rom-com game that you can play in one evening.
