You will have three new daily missions every day. Ensure you complete them due to the fact that they are actually easy (for instance gather X quantities of suns, or get X quantities of containers of popcorn) and you can complete them if you just pay a bit attention to the game. The daily missions that need you to gather "precisely" X quantities of suns will require you to crash a wall or pass away in some way after gather that amount, since else the mission will stop working. I recommend paying rather a lot of attention to these, and if you believe that you can't do it, just skip it.
