You are reduced to DNA, the ball falls down, and all of this for nothing.
At the very end all that is left after stage 4, is DNA. There is nothing but limbo left, oddly it's not alien at all, it's still familiar and you remember where to go. Remember that you chose to come and visit real hell of a videogame world, if the player wants to, they can just be done with stage 1. To cause absolute pain and suffering unlike just completing the 1st stage. But we can still make out the map and make out the familiar, we repeated the same cycle but 4 times, and worse every time. The only surviving elements are hope, player's will, the ball and frustration. At the end you are left with absolute darkness, no naration, no music, the game's world is dead, emptiness of once enjoyed and interesting designs is gone. Apparently the full game is the same map chopped, destroyed, demented, and hidden away from public view for 4 stages. Everybody is happy that they have finished this game, but little do they know that it's only 25% of the full game.
No wonder only there is only one video proof of the 4 stages existing.
