Is the source available somewhere ?
(I'm still learning Axe)
If you're still interested, I uploaded a new version to ticalc with the complete source.
It should be up in a few days.
Besides, the 'touchpad' can be made better if you wrap a piece of paper around the control keys.
I'm going to have to try that at some point
That's pretty clever.
I just wondered how the high score is saved.
There is no App Var and you can't reset the high score. 
The new version (again, will be at ticalc.org in a day or so) now allows you to reset the high score by pressing DEL at the menu. Hope that helps!
It must be saved to the program var itself, because when I transmitted the game to another calculator
the high score was still there. 
Yes, it's saved in the program itself. There's a complete tutorial on how that works
here.
But as I said, you can clear the high score now. Cheers
EDIT: Meanwhile if anyone wants the source:
http://clrhome.org/fruitninja/Except for A.8xp and FRUIT.8xp, anything that ends in .8xp or 8xi is source.
