Solution to "Heist" by Andy Phillips.  Solution by Dale Johannesen.
For game release 2.  Serial number 970901.

This cannot be an exact walkthrough, because many puzzles have
random elements. I give general directions in those cases.
Solution takes about 1000 moves.

Most of the puzzles are logical, but there are a few unfortunate
places where it's obvious what you should be doing, but guessing 
the right syntax isn't trivial.  I had particular trouble in the 
ocean area and the toy factory.  You will die sometimes, but not 
as often as in Time.

The game's author is British, but seems to be aiming
at a compromise style; one car has a "trunk" and a "bonnet" for
example.  The game generally accepts both British and American 
variants (good work); I use American below, since that's what I am.

(You now have 5 photos, plus the one in the frame.  Each photo leads
to a new game section.  The "student" must come last, but the others
can be taken in any order.  To activate a photo, put it in the
frame and "kiss photo".  There was a hint for this in Uncle's
recording, but it still seems pretty obscure to me.)

(Toy factory)
u. x desk. open drawer. look in drawer. get drawer. look in socket.
get terminal and cylinder. x poster. (Oh no!  Murdering millionaires,
knocking out guards, stealing from jewellers, and electrocuting dogs
are all in a day's work.  But a nude woman, now that's distasteful!)
d. w. x machinery. x panel. push button. put cylinder in input tray. 
set first slider to 2. set second slider to 3. (These numbers might
vary; if necessary, experiment with the sliders until you get
two points by pushing the button.  I don't think you can break anything
by repeated experiments.) push button. w. enter booth.
(The idea is to maneuver the arm so it puts the cylinder inside the
can.  Walk in the main compass directions to move the arm. "jump"
to raise it, "crawl" to lower it.  When it is right on top of the
cylinder, "spin".)  out. look in output. get spray. e. e. s.
open box. get doll and cotton and ring. move box.
x doll. get doll's head. pry manhole with spike. d.

(Change the spinning shape to match the color and shape of the id's 
logo.  Turn the rim of the paint can to change its color, then 
"spray shape". "touch" the shape to change its shape.  Then:) 
enter tubes. (Similarly, spray the hair and eyes of the bust to 
match yourself.) x bust. x symbol. (The symbol can indicate either
male or female; "turn" it to female if necessary.) enter door. u. e.
show id.

(Stealing the Crown Jewels)
z. (until you've "nearly reached the ground floor".)  spray man.
get gold key. w. read sign. (and note the time indicated.) x door.
(To open the door, put the metallic shapes in the correct slots.
You guessed it, this varies.  When each shape is in the correct
slot, the number on the left will match the number on the right.
Each number is divisible by the number of sides of the correct
shape (or 10 for the circle), so not too much experimentation
should be required.  When you're done, the vault opens.) s.
x hatch. put silver key in left keyhole. put gold key in right keyhole.
tie cotton to silver key. tie cotton to gold key. pull cotton.
look in panel. x watch. plug terminal into socket. push switch.
(You're at the upper left of a "maze" that looks like 4 figure-eights 
connected horizontally. This is a digital time display, currently
showing the time on the stopwatch. The idea is to change the time to 
match the time on the sign. Touch the spheres to turn them on or off. 
It's a 24-hour clock, and a leading zero may be necessary.  When 
you're done, return to where you came in, and:) d. (If you did it
right, the laser beams will go off.) x jewels. get mace. get arrow.
