Comet Isle, July 6th is about the lives of 50 characters on the titular island and over the course of the single titular day. In other words, it is 50 stories running in parallel, interweaving, clashing, and hurtling toward the Isle's ultimate fate.
Every character is the protagonist of their own story, and a side character in many others. Each story is fully playable on its own with Bad and Good Endings, to avoid and to reach. Some as simple as solving a mystery or eating a good meal, yet others as impossible as stopping a comet or confessing a love.
Swap between perspectives as easily as flipping through channels on TV. In a character's perspective you can experience their daily life, control their actions, view their Mood and Schedule, and be privy to their innermost thoughts.
Decisions propagate throughout the Isle, rippling the stories of other characters. A fleeting moment, a shift in mood, an unspoken word, can all change the fate of the island.
Solve the puzzle of causality and chaos. Trying to reach the Good Ending of one character might lead to the Bad Ending for another in a convoluted web of events. If a Good Ending for all 50 characters, the hypothetical Perfect Ending, exists, it will require a mastery of perspective swapping and time rewinding, and a deep understanding of each character's personality and motivations.
