The input screen works fine over here!
However there is a much larger problem in your code... you don't seem to understand arrays, or you're used to using a different programming language

.
Instead of making an array for each variable... make one or two! Or use a type.
Stat(20) for example. And Stat(1) is your health, Stat(2) your armor, etc. Much friendlier on RAM and eaiser to use and remember, and it's less code!
Remember arrays go from 0 up, not one up

.
If you're just using a variable-- like gravity-- don't put (0) there. Just let it be a variable, not an array!
I've taken the liberty of arranging your arrays a bit... you can change them all around of course, but since I made a fairly detailed RPG system with an inventory and equipment system two times, you might want to follow that path

.
I'll attach the fixed-up code.
Oh... it's speled 'labyrinth' by the way

.
If you want the code for a mouse-oriented menu, I'd be glad to post it.
Cheers!
