level editor

[Usako]

I just made a simple level editor with c++/directdraw and I was wondering if everyone could run this thingy without problems.
The url is (now als including zippies! *smile* (ignore the game.rar, it's infact the editor O_o):

Controls are quite simple:
Mouse for scrolling
Arrow Keys for tile scrolling
f1 for saving
f2 for loading (if you download it, try pressing f2 and you'll see an example map ^_^...loading in the game itself is f1 ).

The graphics are ripped from graal :P (http://www.graalonline.com, please don't sue me )

Any suggestions for improving and stuff are welcome ^_^.
