How do you make your app open up at the main menu everytime?

When my app is opened for the first time it opens up the main menu. When they close the app while playing a level and then open it again it opens on that level. How do I make it open on the main menu every time they open it? Please help this is a real problem because if the app freezes on a level, It will be frozen on that level forever. Also, how can I keep my app from crashing?

As far as keeping your app from crashing you need to optimise its performance.
What are you GS Viewer numbers like?

Okay so my numbers are definitely not good... The total starts at about 25mb but goes up about 3-4 mb for each new level. For example, it is already at 61.4 mb by level 11!!!!!! How do I fix this?
Thank You.
