Although I tried to place a few 8-level buildings together, it doesn't combine and turns into 9-level building. I've restarted the game for about 10 times and really depressed abt that

I don't understand, I just downloaded the game and when it starts, I can see islands... And few seconds later, nothing happens... A window appears with choices to close or continue and wait an answer by the program... Do you understand what I mean ?

it says tracked controllers

how you get the Grandmaster achievement?

Is there no high score record so you can see your own scores !
