Check out this cool video demonstrating peculiar game mechanics in Object Impermanence, a captivating Unity-based game where objects stop existing or moving when you don't look, developed by Slugware.
The game plays with the idea of object permanence, which implies that objects continue to exist even when they cannot be seen, heard, or touched. In this puzzle game, on the contrary, things disappear or become motionless when you don't look at them. These unusual mechanics allow for coping with the in-game obstacles, such as crossing the railways with a moving train, like in the video above.
