download an ini lib or learn how to do it yourself, but you basically make a ini file with a list of unlocked levels. i suggest
level1=unlocked
level2=unlocked
level3=locked

and so on...
you just get weather level(whatever)=locked or unlocked...

i looked at your code ad it seems you have alot of pointless things, i could do it for you, just give me the editable gmk/gm6

HUGE bug, no idea how to fix.
when the block's lt and wt are not equal to each other(32x32,128x128) the larger side goes on for about 2000+ pixels/or what ever so if it was 256x32 it would draw a 256x32 block/plat but you could would not fall off at the 256 side, you go on for about 2000+ pixels like i just said

all you did was move around in a box and if you presses space another charter was added if you hit the an outside wall you stopped

thanks pinpickle, credits to you

yes, use this code:
if x > view_xview[argument0] && x < view_xview[argument0]+view_wview[argument0] && x > view_yview[argument0] && y < view_yview[argument0]+view_hview[argument0] then{
dont 4get 2 add an } at the end XD

Thanks, credits to you
