'LumineNight' is a mystery adventure game set in the city of Summerset, USA, in the 1950s. You can play as Detective Kelvin Foster and his only daughter, self-proclaimed Detective Selen Foster, to unravel the secrets of a series of unresolved murders over a decade.

Players need to investigate, solve puzzles and codes, infiltrate, interrogate, and deduce the truth, all based on the following five detective principles:

1. Find Clues in Dark Streets

In a corrupted city's darkness, the detective's eyes are the only thing you can trust.

In the deep night, the neon-lit streets are filled with truths yet to be uncovered.

Gathering raw evidence is the mother of all detective work.

Detectives who pursue the truth prowl through the city in the night's darkness, gathering even the slightest clue.

2. Use All Your Senses to Unravel Tricks and Codes

Nothing can stand in the way of those seeking the truth.

A piece of advice from a father to his daughter, a genius in deciphering codes.

Riddles and puzzles encountered during the investigation, doors that are firmly locked and won't open, codes containing secrets that penetrate all truths...

Everything awaits the touch of a solver.

3. Sneak among the Shadows

As a detective, sometimes you should act before getting permission.

When you secretly infiltrate and bypass strict security, you might be able to access crucial clues.

4. Prove Contradictions Between the Crime Scene and Testimonies

If there are manipulated traces in the crime scene or testimonies that do not align, you can verify the contradicting aspects through interrogation.

When you refute the contradictions with your logic, the masks of those riddled with lies will be stripped away.

5. Complete the Deduction

You can deduce the beginning and end of all incidents, the reality behind secrets, and what each character wanted to hide.

Revealing the truth now depends upon you.
