what is up with level 70 of 100 floors, how do i get the alien on his ship?

Level 70 of 100 Floors is one which you really need to write out if you intend to figure it out for yourself.

In this level there are a series of rooms from which you can move left or right by pushing giant buttons on the floor. The buttons don't necessarily take you where you might think, which is why you need to write down to which room every other room leads, both left and right.

You need to enter every room in order to complete the puzzle.

If you don't want to do it yourself, we've written the connections down for you; the center number shows the current room, and to the left and right are the connections:

• 05<-01->02
  10<-02->07
  09<-03->10
  08<-04->01
  02<-05->07
  01<-06->11
  03<-07->05
  02<-08->06
  01<-09->04
  02<-10->05
  

In case you don't want to figure it out for yourself, here are the exact moves; tap the buttons in the following order: Left, Right, Left, Left, Right, Left, Right, Right.

That will get you to the alien spaceship, and on your way to level 71.

If you haven't updated the game yet, on June 12, 2012 version 1.4 was released bringing the total number of levels to 80.
