The ending is bugged for me, when I 'fall through the floor', and after that and the screen going black, I don't teleport to the kitchen next to the radio, the black screen fades to me being in the caves still. I 'presume' its related to my hz/framerate messing with the coding maybe? Otherwise no idea what else could mess with the game to make it so the ending is messed and I get stuck in the cave area with no way of escaping - but I do hear the radio.
