Proceed to the exit. Should you feel any sense of unease, you may turn back.

About This Simulation
This simulation is an observational experiment designed to train an AI to follow the instruction: “Proceed to the exit, and turn back if you feel something is wrong.”

As the player, your actions will be directly observed and learned by the AI.
Various “exit”-themed objects are placed throughout the stage.
Please proceed forward unless you feel any discomfort — and turn back if you sense something unusual.

When the observation count reaches 9, the AI will have completed its learning process.

Note: Gameplay streaming and full playthrough videos are warmly welcomed.

How to Play 

This is a 3D spot-the-difference game.

If there are no differences, proceed toward the direction marked "EXIT."

If there is a difference, go in the opposite direction of the "EXIT" sign.

Correct actions increase the counter shown at the top-left of the screen, while mistakes reset it to 0.

Reach a counter of 9 to clear the game.
