#15
We Went Back is a space-station time loop where the same hour keeps resetting, and each loop the environment has changed in ways that should not be possible. It is visually polished, the horror builds through repetition and environmental storytelling, and the whole thing is completely free. I got through it in one sitting of about an hour. The brevity is the honest limitation here: there is not enough runtime or replay value to sit alongside the stronger entries on this list, and the story wraps before it fully earns its atmosphere. Worth an evening if the concept appeals, but not a list headliner.
