+ <h1>Depths of the Mind</h1>
+
+ <p>
+ The mind is an intricate thing, with many tiny components working together
+ in perfect harmony... Until something came in and messed everything up!
+ </p>
+
+ <p>
+ If you want to set all the pieces of the mind right, you'll need to know how
+ it works!
+ </p>
+

+
+ <p>
+ The structure of the brain consists of black blocks filling a white void.
+ </p>
+
+ <img src=
+#include "../build/tutorial_red_yellow.png.b64"
+ >
+
+ <p>
+ Black blocks will turn red when clicked (if you have red in your inventory on the left).
+ While the brain is running, black blocks next to red blocks will turn red!
+ Red blocks will eventually tire to yellow, and then back to black. They don't stay red very long!
+ This is what allows the brain to send signals along a series of black blocks.
+ Yellow blocks can be placed with a right click on a black block (if you have one in your inventory)
+ </p>
+
+ <img src=
+#include "../build/tutorial_direction_red.png.b64"
+ >
+
+ <p>
+ Sometimes, only one side of a block turns red.
+ When this happens, it will try to move in that direction (and leave a yellow behind it)
+ but if it cannot it will turn clockwise and try again.
+ </p>
+
+ <span>
+ <img src=
+#include "../build/tutorial_blue_1.png.b64"
+ >
+ <img src=
+#include "../build/tutorial_blue_2.png.b64"
+ >
+
+ <p>
+ Blue blocks need to be moved around to keep things running smoothly!
+ When a blue block is touched by a single red block, it will start rolling
+ away from it.
+ Each level has a goal in faint red which needs at least one blue block to be delivered to it.
+ Some levels will also have faint blue areas that create new blue blocks for you!
+ </p>
+
+ <img src=
+#include "../build/tutorial_blue_clone.png.b64"
+ >
+
+ <p>
+ Finally, if a blue block touches a red block <em>while in motion</em> it will be cloned!
+ One will be left behind and the other will continue.
