THE FIRST ROOM:
The order you play the levels in doesn't matter. After all of them are
complete, exit the room to the north.

NORTHWEST HEAD:
There are two separated mazes, which you can tell apart because the "walls"
are facing opposite directions. You start inside one maze and the goal is
inside the other maze. Just follow the left-hand or right-hand wall until you
are outside the maze you start in and can see the other one, then follow the
right-hand or left-hand wall around that maze and you'll get to the goal. The
top and bottom of the map are endless loops that do nothing.

NORTHEAST HEAD:
There is no specific trick to solving this level, just timing. The collision
hitboxes are smaller than a full tile, but don't expect to be able to cross
every narrow gap. 

WEST HEAD:
The shortest solution is five teleports: use the hands pointing up, left,
right, up, then down. If you make a mistake in that sequence, it may be faster
to press R and re-enter the level from the start than to find a different
route.

EAST HEAD:
The tiles are arranged in an almost exact 3x3 grid. The head is assembled
at the central tile when you get the other tiles.
One possible fast solution is:
1. go down from the start and get the bottom-center tile, starting the timer
2. go left and get the bottom-left tile
3. go up and get the center-left tile
4. go up more and get the top-left tile
5. go right and get the top-center tile
6. go right more and get the top-right tile
7. go up and get the bottom-right tile
8. go up more and get the center-right tile
9. go left and get the completed head

SOUTHWEST HEAD:
The horizontal corridors move rows and the vertical corridors move columns;
the small squares on the ground near them are intended to hint at this.
The row or column moves in the direction that you move through the corridor.
The initial state of the puzzle is intentionally easier than a random shuffle
would be. The shortest solution is:
1. go left through the middle horizontal corridor to shift the middle row left
2. go up through the right-hand vertical corridor (shift the right column up)
3. go down through the middle vertical corridor (shift the middle column down)
4. go down through the left vertical corridor (shift the left column down)
5. touch the completed head

SOUTHEAST HEAD:
There are several different effects that the marked tiles can have, and some
marked tiles with no effect at all. There is no visual difference between these
different tiles. The only variables used are which tile you are on, which
input direction you press, and which direction the "walls" are facing. It does
not matter whether you use the arrow keys or WASD, and time does not matter.
There are 11 sections of marked tiles to pass through, as follows:
(the sections are not numbered in-game)
1. controls are rotated 90 degrees clockwise; press up repeatedly
2. controls are reversed; press left repeatedly
3. alternating stripes of rotate and reverse; alternately press up and left
4. checkerboard of rotate and reverse; on the top row, alternate left and up
5. alternating stripes of reverse and no-effect; alternate up and down
6. two-tile-wide stripes of reverse and no-effect; repeat down down up up
(after 6, there is an oddly-shaped area which is a hint about the #9 path)
7. no effect, just keep pressing up
8. when the "walls" are facing left or up, this section has no effect,
   but when they are facing down or right, this section reverses your controls;
   pay attention to the "wall" facing and press up or down accordingly to get
   to the bend in the corridor, then left or right to continue through it
9. some tiles move you right no matter which key you press; enter via the
   second tile from the top, then in the middle column move down twice to leave
   via the fourth tile from the top
10. these tiles just move you right no matter which key you press
11. some tiles move you right no matter which key you press; stay in the bottom
    row until you can't proceed, then the top row, then down three tiles
    to the fourth row, then the top row again, then down to the head when you
    can reach it

SECRETS:
There are no alternate endings, secret collectibles, or other optional hidden
game elements. There are some unique graphics in obscure places, but none of
them are specifically there as Easter eggs and the game does not keep track
of which ones you've seen.
