The levels are easy enough. The bonus is the hard part. Think outside the box. Don't follow the path and then try to get the bonus. Jump onto a different platform.
HINT: The narrow platforms can't change gravity, but you can still jump on them.
There is no "save button". It saves at the beginning of each day. Now, if something happens at "6 pm" on a great day you are screwed. But you only have to start that day over.
