Manual

In a nutshell

Start with the 3d version.
Mousedrags make turns. Shift+mousedrag moves forward/backwards. The cursor is the black +.
From there on, just play and see what happens.
Once you get the hang of it, try the 4d version.

Moving around

Use mousedrags to move around.

Key	Mousebutton	Drag	Movement
Shift	1	Up, Down	Move Forward, Backwards
	1	Any	Turn
	2	Up, Down	Turn Ana, Kata
	3	Clock	Clock

Note the third mousebutton is the right mousebutton on a right hand mouse!

Clock stands for rotations perpendicular to your view.

Alternatively you can use the keyboard cursor keys. Use Ctrl for third mousebutton and Alt for second mousebutton. (If Alt + Cursor is already defined for your system, try Ctrl + Alt + Cursor).

Playing the game

The cube is hollow on the inside and transparent but solid on the outside. Try not to bump into it. A red line shows how you've hit it when you do. Kick the big ball with the cursor aiming it at the target. Five targets to hit per game. After a hit you must earn a new target first, by moving the cursor through the window. On the outside, stay clear from the small ball. A red line is thrown when it got you.

Score

+100	To start with.
+100	Hitting the target.
-1	Each second.
-10	Bumping into the cube.
-5	For approximately each second a red line is thrown by the small ball.

Have fun!
