About this game

A creepy looping street where each pass has a chance to have an audiovisual anomaly. Players must decide to go forward if they haven't spotted, or go back if they have spotted an anomaly in the current pass. After 9 correct guesses in a row player wins the game.

Each anomaly is strange, sometimes bizarre, sometimes scary. Wrong enough to make your skin crawl.

Miss one, and you're back to the beginning.

With randomized anomalies each run, every playthrough feels different.

Controls:
W/A/S/D = move
Shift = run
Space = jump

Playtime (each playthrough):
15-60 minutes

Final words from the developer:

This game was made with love. I created it because I genuinely enjoy anomaly detection walking simulators. The Exit 8 and Shinkansen 0 were major inspirations, and I wanted to build something in that spirit.
