I put the credits at the beginning so you migh actually read them,
even though it's most likely by accident :P.

More detailed explanation:

Antrun is based on the puzzle game of the same name for the PC by 
Solei software (if I'm not mistaken).

The rules of the games are only slightly different than those of its
PC ancestor:

The object of the game is to let the ant* cross as many tiles as
possible. You get one point for each tile you cross. The ant just 
blindly follows the road on the tile, and keeps walking until it 
bumps into a solid wall, and then the game is over.

Whenever the ant has crossed a tile it becomes a solid wall, so 
in the end you'll run out of tiles to cross, right? Wrong! 
Whenever the ant crosses the borders of the maze the black tiles
are reset with random normal ones. In the beginning these are always 
"good" tiles, but every time you cross the border the  chance of a 
useless solid tile being spawned increases. This chance** also 
increases as your score gets higher, although much slower.
Also, the four crossroads don't turn into black tiles when the ant
has used them, so you can cross them multiple times.

So how do you make sure that the ant doesn't bump into a wall? By
rotating the tiles ofcourse. pressing the 2nd key rotates the tiles
the cursor is on. Moving the cursor is as simple as pressing the
arrow keys (it can handle diagonal movement, btw). The cursor wraps 
around the screen too, which might be useful if you want to get to 
a tile quickly. The only restriction is that you can't rotate the 
tile the ant is on.

To quit the game you can either lose or press Mode. Simple as that.


*  The ant is just a pixel, so if you prefer to imagine 
   a rat, spider or even a cephalopod, be my guest.

** If you survive long enough (really really long) you
   might even notice the game slow down a bit as the 
   randomization routine takes longer to execute :)
