TIPS
1) Food items that fill energy's bar:
Cake(Bakers) ---> Wally
Apple(Bar) --> Dick
Coke (Butchers) --> Tom
Coffee (Wally's House) --> Harry
Sandwich (Workshed) --> Wilma

2) Food items appear at this order:
1st. Bakers & Bar
2nd. Workshed & Butchers
3rd. Bar & Wally's House
4th. Butchers & Bakers
5th. Wally's House & Workshed

(when you pick one of the items in 1st place of the list, the other disappears and the next pair of items appears)

3) Places where other characters can't pick up items you drop
-School
-Butchers
-Park
-Supermarket (Tom must repair trolley and only Harry can pick/drop items)
-Top of the wall (in Wall Street)
-The docks (it can be a good place to drop meat/gas mask while hook is broken)

4) The combination of the safe
B: Wilma
R: Tom
E: Dick
A: Harry
K: Wally

SOLUTION
How to finish game with maximum score (£3000)

(1) REPAIRING FOUNTAIN
[start with Dick (key '4')] right, enter post office, get plunger, exit building [move right], right, enter bakers, recharge energy, get monkey nuts, exit building [move right], left[x4], enter zoo, get wrench -you've to drop monkey nuts-, exit building, right[x2], reach top of fountain to repair it.

(2) REPAIRING HOOK AND BUILDING A WALL
[change to Wally (key '1')] go to docks, get hook broken, enter sewer, use left ladder to exit [appear at park] -be fast, the shark can kill you-, left, right, enter lab, get superglue [at this point of the game nobody has picked it up, but if you're slow Harry can get that item and you'll have to force him -using key '5'- to drop it ], exit, left[x2], enter workshed, place hook on the left table and superglue under that table. Pick superglue and then the hook -'the hook broken' becomes 'the hook working'-. Get trowel -you'll need later-. Return to docks [using sewer] and drop hook there. (now Wilma can get the letter 'E' and drop it at somewhere else).
Use the sewer to reach park and get the sand -you must drop trowel-. Look for the bucket (normally one of the characters has it), and fill it at the fountain -on your way to the fountain you can look at Wally's House or Butchers for recharging energy without risks (if you need)-, right, jump to enter phone box and enter an Asteroids game [left&right: rotate spaceship, up:go straight and jump:fire]. A tip for this game: destroy rays that move diagonally first, they're the most dangerous. You've to destroy rays until you hear a beep (when that happens rays in pylon's screen will start to move around all screen), exit using left square (the screen with library). Up, jump fire -it will disappear when Dick repairs gas-, left[x2], right[x2], get cement -optional: take a look in work shed if you need energy-. Next step is to get trowel (you left it at the park (path from here is: left[x2],up[x2]) and then left[x2], right to be at Wall Street. Walk right till you build a wall. (you've almost finished with Wally, the last thing you've to do with him is to get letter 'K' and end the game).

(3) ELECTRICITY (I): REPAIRING PYLON & THE FUSE
[change to Harry (key '5')] Look for good insulator and screwdriver. When you've those items, reach screen with the pylon and repair it -it's like the fountain, but this time you'll have to get the cracked insulator-. (you can do this because Wally destroyed rays before in space -although anybody could do that-). Look for one (or more) places to recharge energy -start looking at Wally's House-.
Continue with Harry. Look for fuse wire and get fuse blown -it's at butchers, nobody can get it- to repair it. After you do this everybody will be able to get the meat. [tip: if you find gas mask while you search fuse wire, leave it at the park -Dick will need later-] Important: You can repair fuse only at butchers.

(4) PARCEL STAMPED
[change to Wilma (key '2')] Look for rubber stamp and parcel unstamped. Enter post office, walk to the left (important: only Wilma can do this). The parcel becomes stamped. Now go to the docks and drop parcel there -you get letter 'E' (Dick's letter)-. Drop the letter in a safe place (example: park, butchers,...).

(5) FIRST LETTER
Continue with Wilma. Next thing is to place books '1', '2' and '3' at library. When you place 1st book at the table drop jump leads at School (for example) -you'll need them later when you control Harry-. When you've finished with the books, you get letter 'B'. Exit library, right, enter Bank and go to safe. Exit building. [you've finished with Wilma]

(6) REPAIRING GAS
[change to Dick (key '4')] Go to butchers and get meat. Look for gas mask. When you've found it, go to sewer. [if you see somebody entering the cave, wait for him/her to avoid surprises ]. Drop meat. Go to docks [use right ladder] and get the hook -be sure gas mask is the 1st item and don't lose it when you get pipe-. Return to sewer. Enter the cave. Get pipe -remember to jump letter 'R'- and exit -jump letter again-. Get meat again, exit to docks. Drop meat here -nobody will get it-. Return to sewer and use left exit [the park] -this time the shark can kill you, so... climb fast-. Next step is to repair pipe. Drop gas mask at park [nobody can get it from here], drop pipe at school [nobody will get it from here] and look for patch and chewing gum. Carry those items (pipe, chewing gum, patch) at work shed (pipe must be on the table). Get patch and gum and then the pipe. (With this you've repaired pipe). Return to the park to recover mask. Drop mask at sewer. Recover meat at docks and drop it at sewer. Before entering the cave be sure your 1st item is gas mask and the 2nd one is the pipe. Jump letter 'R', drop pipe -fire disappears and you won't need the mask- and get letter 'R' before you exit (you won't have to enter here more times). Exit sewer by right side, drop letter 'R' at docks -an easy place to remember when Tom needs the letter- and drop hook (working) at next building.

(7) SECOND AND THIRD LETTER
[change to Tom (key '3')] Look for hook and place it at docks (you get letter 'R' -Dick dropped there-) and return to the Bank. Go to safe, place letter and exit building.
[change to Dick (key '4')] Find letter 'E' -Wilma picked up at docks a long time ago- , go to bank, enter, go to safe, place letter and exit building. [if you have one of these: bottle, bunsen burner or matches drop it in a place where Tom can pick it up.] [You've finished with Dick]

(8) FILLING BOTTLE AND OIL
[change to Tom (key '3')] Look for bunsen burner, matches and bottle and place them at lab. First, the bottle must be at right table, get bunsen burner and matches and then drop the burner at other table. Exit and enter -if you don't do this, bottle won't be full-. Get bottle, exit building and enter bar, change bottle by money and exit -recharge energy if you see the chicken leg (although it won't fill the bar to this character)-.
Look for oil can and then go to garage to fill it (that will happen when you reach oil bottles). Exit building. Go to market and use oil on trolley (it starts to move, remember a detail: if it touches you, you lose energy).

(9) ELECTRICITY (II): THE BATTERY
Continue with Tom, go to Wall Street [the path is: left [x2], right], get battery, return to the garage and drop battery (Harry will recharge it later). [change to Harry (key '5')] Get jump leads and battery (Tom dropped it at garage, it isn't a 'safe' place but normally nobody has enough time to get it). Recharge the battery and drop it at the same place. [change to Tom (key '3')] Go to Wall Street and place the battery charged. Use truck to climb onto the wall, get letter 'K' and drop it at park -Wally will get it later to finish the game -. [You've finished with Tom]

(10) FINISHING THE GAME
[change to Harry (key '5')] Go to supermarket. Jump over trolley and get letter 'A'. After this, you've to go to bank and reach the safe. [You've finished with Harry]
[change to Wally (key '1')] Go to park, get letter 'K', go to bank and reach the safe. [You've finished with Wally and opened the safe. THE END]


BUGS
Tom can repair the trolley with the oil can empty.
If you've fuse (blown) and fuse wire outside butchers you can't repair the fuse. You must enter that building to repair it.
