I’m just kinda throwing this idea out here at 1 am. The idea is that the animation reaches the point of the astronauts being in space and a serious problem occurs with the rocket, as reflecting the explosion of the rocket at the start. Then the mc wakes up again and the whole plot from last waking up repeats but at high speed. Then again maybe. Cut to clean plain white depthless environment with a single weird item that resembles the lamp of a victorian streetlamp roughly glowing Blue. Part of the thing bursts off at high pressure and the mc is thrown out of the thing. He is living in a repeating fake reality.
