What a great submission! I got 4 of the endings so far — a really impressive amount of variation for a 48-hour jam project! The intro cinematic has a few rough edges (for instance, some clipping through objects and a bit of camera drift), but the overall quality and the strong voice acting & atmosphere make up for it quickly.
What stands out most is the tension between stillness and urgency, which really captures the “Timeless” theme beautifully. The countdown mechanic creates genuine pressure, though why are the two robots not frozen in time, while the one carrying the cube is?
The Endings are currently not really shown what kind of "impact" they have, if you plan to build this game into a full release (which I hope you do) consider adding an outro that matches the quality of the intro.
