Jupiter-Saturn: Testing Conviction

Jupiter-Saturn: Testing Conviction is a visual novel about an eccentric scientist and his companion, who are abducted by agents acting on behalf of the state. Their captors pressure them to defect to the country that kidnapped them. Your choices shape the plot’s pace and direction, while backstory and other details emerge gradually, leaving mysteries to unravel.

Story paths

The story has multiple paths and three playthrough styles, each with its own ending. Seeing every ending requires playing through the game in its entirety; one ending is not enough to fully understand the story.

• Negative: a very fast pace, many scenes of violence and swearing, and revelations about secondary characters.
• Neutral: a measured, calm pace, with a low or moderate amount of violence and swearing depending on your choices. This path answers the main plot questions and focuses on the protagonist.
• Positive: faster than Neutral but more measured than Negative, with minimal violence and swearing. The story increasingly focuses on one of the secondary characters.

Reading and choices

You spend most of the game reading dialogue and periodically choosing from the options presented.

Art and sound

The backgrounds and characters are hand-drawn. The art sometimes exaggerates proportions and shows scenes from unusual angles, while selection buttons are styled to match each scene. Animations are rare.

Ambient music accompanies most of the game, creating a cosmic atmosphere, with other tracks for events ranging from brutal confrontations to everyday tasks. Most events also have sound effects, including doors opening and the protagonist’s footsteps.
