Controls

One joystick and two keys

The joystick moves Toki, jumps, and fires. The keyboard has two commands, and a third combination is hidden.

Input	What it does
Joystick left or right	walks left $8727 or right $8703
Joystick up	jumps straight up $8840
Joystick up-left or up-right	jumps to that side $86D4 $869A
Joystick down	on a block that allows it, hands Toki to the second movement routine $87D5
Fire	fires a shot $AF34
RUN/STOP	pauses and resumes $5290
SPACE	switches between sound effects and music $5290
Both joysticks, then the Commodore key	skips a stage: the hidden combination

The game reads joystick port 2 each frame, and reads port 1 instead when port 2 is idle $8572. The four direction bits become a direction byte, and the fire bit becomes a flag, which the movement and shooting routines read.

Shooting

The stick picks the aim

A shot goes where the joystick points when fire is pressed.

On the ground, up aims straight up, up-right and up-left aim diagonally, and right and left aim sideways $AF34. Any other direction aims the way Toki faces. Each weapon record holds one path for every aim direction, so a weapon can send its shots differently in each of the eight directions.

Jumping and falling

The speed of a jump is a table

A jump rises quickly, slows, and falls faster the longer it falls, all from two small tables.

Table	Pixels per frame, by counter value from 0
Rise $02CE	1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 4, 6
Fall $02DF	0, 1, 1, 2, 2, 3, 4, 5, 6

The routines for the rise $877A and the fall $87B8 take their step from these tables and move the player's trial position. The rise counter holds the height left to climb and counts down, and any value above 16 reads the last entry, so a jump starts at 6 pixels a frame and slows near the top. The fall counter starts at 0 and stops rising at 8, so a long fall tops out at 6 pixels a frame. The normal jump starts its counter at $38 $08FC, and a jump out of the second movement routine starts it at $10 $922F.
