The game uses a simple gameplay of flipping cards to simulate the exploration of the streets at night.

Each location on the street has a different number of cards, and players must click on them in a reasonable order to pass through.

Different cards have different effects including attacking (mental damage), healing, damage-immunity and so on. Clicking on them in a reasonable order is the key to success.

Of course, you can also use skills to shuffle the cards. In addition to shuffling, you will also gain more skills during the game, which can form diverse and powerful combinations to help you overcome various challenges.

Skills come from different characters and you will encounter them in various locations during the game. Meeting those characters will drive the story forward until the end of the night.

Or... will it ever end?
