Ok, so I've updated the game. It looks like if you play a game too much it becomes too easy then you end up making it too hard.
Changes are as follows:
Space Bar - Rotates pieces
S Key - shovel/construction piece for fixing track
F Key - Start the ball rolling fast
P Key - Pauses game.
Play through the tutorial, it will help you understand how the game works... Once you understand how to swap/grab/place properly the game becomes much more easy/enjoyable.
I should be more clear about what button to click. After you click "Play" you will be taken to another menu with all the levels to select, then click the "More" button in the bottom right.
@jahguy7: People can make and save their own levels to the server for you to play. Just click the "More" button and you will be taken to the list of levels... Although they are really lacking, I think making a level is harder than most people realize.
Thanks for the comments.
The first level says there is a Skip button in the menu, but there isn't.
I took it out in case they want to make a completed the game badge and didn't want people just skipping to the end.
