Rotate the train so that east is at the top of your compass. Move forward and switch tracks when you come to the first intersection. The train will stop itself. Press the center button to dig a hole in the rock. Get out and walk through the hole. Look at the diagram in your inventory to see the cannon. Look at the table and click on the wood piece. You are going to make a cannon, which can be very frustrating and tricky.

The 7 parts of the cannon are: lightbulb, barrel, box with handles, mouse-like object, ball with 3 arms, wood piece, crystal bottle. The order that they are displayed in the cannon screen (from left to right) is: mouse-like object, barrel, wood piece, box with handles, lightbulb, crystal bottle, ball with 3 arms. You're going to combine pieces to create the cannon. Put the lightbulb and the barrel on the screen. Turn them so that the plug of the lightbulb faces the barrel and that the barrel's tip faces the lightbulb. Move the lightbulb and click it on the barrel's tip. They should click together, if they didn't adjust the alignment and retry. Put the box with handles on the screen. Rotate the combo pieces so that the lightbulb faces left. Rotate the box with handles so that the broken handle faces the combo pieces. Move the combo pieces over the box with handles and they should combine. Move the mouse-like object to the screen. The ears can be clicked to three positions. Make sure the ears are in the center extended position. Turn the mouse-like object so that the pointy side is facing the combo.

Additional info submitted by Adrian Hurt:

In your house, right at the start of the game, observe the names on your phone. Then check the game credits...

The entry combination for Dr. Krick's laboratory is 8-24-96. This is obviously a date, but I didn't find out its significance until I checked someone else's walkthrough page. (I can't remember where it was, now.) Apparently that was the wedding day of one of the programmers.

Dr. Krick should never have told you to throw that bottle in the sea. It was washed up and found by a fisherman who thought it contained a genie who would grant the usual three wishes - not a mistake he's going to repeat. The Dark Being has returned to the Alternate World via Dr. Krick's portal generator and is now back in business, having first released the Birdman and instructed him to do a more thorough job of sabotaging the radio control.

Your mission, should you choose to accept it, is to return to the Alternate World, recapture the Dark Being, and bring him to the Temple for safe keeping. You can not use Martin's radio control. The mission will end when you present the Crystal Bottle to Lyril.

I can't reprogram the game, of course, but Lyril will say something suitable when you show her the filled bottle. While you're there, show her Amanda, too. The result is both very predictable and very amusing - poor Lyril really needs to get out more, but unfortunately she can't...

When you first enter Martin's study (the room past the green gate at the tower, just after you pacify the guard hawk by activating the cuckoo clock), the Birdman might steal something from a drawer. Do not panic, you can get it back by either of two ways. The first is to go up the ladder in the bat hangar (near where you used the key to release the bat). This leads to the hawks' nest. Turn around a couple of times. The Birdman will appear. Quickly press the middle button on the remote control ("Attack"), then press the large "Activate" button. The hawks will attack the Birdman, forcing him to drop what he took. You must be quick, otherwise the Birdman will attack first and destroy one of the hawks; the others will then not respond to the control. (I never did find a use for the third button, "Patrol".) If you are not quick enough to defeat the Birdman here, or if you don't choose to do this, you can still get the stolen object later; he'll still have it when he appears at the Temple, and will drop it there.

In the Temple, there are a number of ways you might upset Lyril - hopefully not on purpose! The worst is to mess with her personal controls. If she gets really angry, she won't want to talk to you. Give her some shells to show that you're not really that bad. (There's another set of shells on a beach outside the Temple. From the Bat plane, move forward, then right. Or, from the main level, return to the elevator, go back down, then go forward until you reach the beach.)

On the Temple top level, the transporter device will start charging itself up as soon as the roof is open. The slider by the power gauge makes it charge up more rapidly, but may overload it. If so, assemble the three bits you got from the crates in the basement, and use the completed part to replace a burnt part in the top control panel, accessed by a hatch at the top right. The best way to charge the device is to push the slider lever to the right, wait until the power gauge is just short of the red, then push the slider back and let the device complete charging slowly and safely. Only pull the bottom breaker, which activates the beam, when everything else is done.

In the Fortress, the aircraft which you repair can take you back to the Temple. After turning the aircraft round and turning the crank, move to the front of the aircraft and get in the cockpit. Click on the handle on the column on the left; this moves the aircraft out of the tower. Click the knob on the right of the control panel; this spreads its wings. Click the T-bar on the left of the panel; this starts the wings flapping. Finally click the big lever on the right; this launches the aircraft. (And don't take too long about it, otherwise the aircraft will discharge itself. You will then need to bring it back into the tower and charge it up again with the crank.)

In the Volcano, it is a good idea to save the game before turning any of the big valves in the boiler room. This is because one of them supplies power to the turntable. If you turn that by mistake, then try to use the turntable, the game will get stuck; you will need to shut down the game (and if necessary your computer), then reload the game and restore that position.

After reversing the train to the bridge and using the crane to lower it, you should return to the turntable and get the train to face east (to the exit with two large metal chevrons). Then return to the bridge, this time facing forwards, so you can see where you're going. (You need to do this eventually anyway so that the drill is pointing the right way.)

That tool you use on the chest in the Dark Being's lab is not a hammer, it's a pick. I'm convinced this is a joke on the programmers' part; you have to pick the lock!

For an alternative ending, do not assemble the bomb. After Krick has gone through the portal, return to the train, then to either the Tower or the Fortress, then by aircraft to the Temple. Find Lyril and show her the captured Dark Being. Then use the Temple transporter to return to Krick's lighthouse.

And for a challenge, see if you can complete the game without using the remote control from the Birdman's workshop. It is possible...
