I played the main game, and it was good. I have a problem with the editor, as when I try to save the screen goes red.
I made a screen though, if you look over it, it should be piece of cake. 15BG15B2AB13AG14AB2AB13AG14AB2AB13AG14AB2AB13AG14AB2AB9A
All of that combined of course.
I tried your Grey, and they're pretty awesome, actually on par with the real game. Well done.
I wonder a bit how hard mine is...
I created another one, but it isn't quite as good.
That is VGChartz LONGEST review. And it's NOT Cute Kitten DS
