You need to use var (http://wiki.inspired-lua.org/Category:var) so that you can store (var.store(()) variables forever. And markChanged() is only to warn the user that he must save, it doesn't actually save anything.

I learnt it by looking at code of other programs ;) To be precise, Pixel Escape.

It's actually very easy, don't forget to check #nspire-lua for additional help. I had the guys from there help me with this and I can also help you now.

l think var.monitor should also be used.

Yep, to prevent the user from hacking into the high score ^^

yep, definitely, on any non wanted var.change, you could rewrite it from a local lua copy :P

It's still quite easy to cheat...
You just have to
1. open the page sorter
2. cut (Ctrl+X) the Lua app
3. add a math editor
4. change your var
5. paste the Lua app

EDIT : I did not see the last part with on.save() and on.restore()... It makes my solution useless
