There are a few ways to prevent/detect cheating, but some might only be possible with the full version of Clickteam Fusion 2.5:
1) Use the INI++ object by Jack Webster in the full version of MMF which allows you to use encryption.
2) Every time you set a value you could set a corresponding value which is a salted hash or checksum of that value (e.g. using the String Parser object or the CRC32 object), then you can check that to see if the value has been changed to detect someone has cheated.
3) Make the values saved one which are hard to guess, e.g. rather than "Level=3" the levels could be named and so to change the level they would need to know the code for the level they want to change it to.
