That map will most likely never be finished. But there is an end to this map. After you past that fading spinning platform, past the door, is a maze. Within that maze is a couple of buttons. One button will trigger a secret door within that maze and display a text "A door has been open!". You will then need to backtrack the maze to its lower platform, a brick wall will disappear. Past that last door is a bit more of a maze but one room will have a button on the Ceiling. After you shoot that button should display the credits "To be continued… [This is alpha test version]" and "Map by Tinman", then the game will end.
