Titans have imprisoned Neptina, Neptune's daughter! They've shattered his magical Trident and scattered its pieces far and wide. Without his trident, Neptune is powerless.
Proteus, a member of Neptune's Court, longs to free the lovely mermaid. He sets out to find the missing pieces of the Trident. He roams land and sea, changing from a dolphin to a seagull and back again in order to deceive the mermaid's captors. Deadly trials confront Proteus -- octopuses, tangled beds of kelp, screaming flocks of black birds, even erupting volcanoes! But he fights on valiantly!

<div class='maintitle'>Scoring Points in Fathom</div><div class='borderwrap'><table class='ipbtable'><tr class='row2'><td>
- The Level number appears at the bottom left of the screen. All games begin at Level 1.
- If you free Neptina, you automatically advance to the next level (2, 3, etc.). Your score for the new Level returns to 50.
- When you free Neptina, the points you earn on the Level are added to the point bank with the total number of points earned on all previous Levels.
- The points you earn are multiplied by the Level number you are on. Example: Earn 50 points on Level 2 and 100 points are stored in the point bank (50 x 2 = 100).

The Manual
As always, you really should read the manual. In case you don't have the manual, AtariAge has a typed copy available online. Here are the hints it provides:
- Run into all the sea horses and pink clouds you can. They're worth points.
- Avoid obstacles -- black birds, grey clouds, octopuses, seaweed and volcanoes. They cost you points!
- Time freezes when the dolphin and the seagull appear on screen together. Otherwise you lose points as the seconds tick away.
- Here's how to fin and fly through Level 1. After that you're on your own!
As the dolphin swims down, octopuses and two sea horses appear. Touch both sea horses. Then touch the starfish that appears. A piece of the Trident now shows at the bottom of the screen. Note: You must reach both sea horses and the starfish without leaving that section of the sea. If you don't, return to the surface and try again.
Next dive through lines of seaweed. More sea horses appear. Touch one and a bird symbol shows at the bottom of your screen. Return to the surface now, or try to reach other sea horses for additional points.
Jump out of the water when you reach the surface. Fly to the left or right. Land appears. Flap your wings hard and fly up. Touch two pink clouds in that section of the sky and a star appears. Touch it. You'll have another piece of the Trident. Return to the dolphin. Fly until you reach land on the other side. Repeat the game of tag with pink clouds. Touch one pink cloud and acquire a fish symbol; touch the other and a star appears. Touch the star and the third piece of the Trident is yours. Return to the dolphin, change forms and dive for the bottom. When you arrive, the mermaid's prison will dissolve.
We played this game once before in the High Score Club, you might want to check out that thread for more hints.
DT Kofoed
- Remember that pulling down as a seagull makes you drop faster.
- It's vital to memorize the starting cloud positions for each screen, so that you enter a new sky screen hitting those low flying clouds rather than low flying birds (or avoiding them as your fall through grey-cloud skies, if you've taken too long).
- I find a free fall along the right side of the sky screens avoids both clouds and birds, allowing you to descend as quickly as the programming allows. Following down the left side will hit birds on the lower two screens if you're in free fall.
Frostbite76
- Collect the pink clouds from the rooms that have the most of them it. If you're in level 6 for example, collect the pink clouds in the sky with six clouds. After you get all six clouds, go down to the sky with 5 but don't get any. Then go back and get the 6 clouds. Keep doing this until the clouds are grey.
- The water levels: go all the way to the right and go down to avoid most of the enemies if not all. Same thing to go back up
- Level 5-7. In the Water go to the 5th screen and collect all but one of the pink things. After you do this go back up one screen then go back down and collect all but one again. Keep doing this until you can't collect anymore. This is the fastest and safest way to collect.
- Study the map after you switch. I can stay there for as long as you want. You can even leave and go back there to freeze time.
- Level 5-7 are the most important levels by far, so be very careful. These are the levels you can really rack up the most points. Level 7 alone can get about 8,000 points. 1100x7. So do not hit the valcano on these levels. It could cost you about 1,000. every time you get hit.
- Fall down from the left side of the screen to avoid grey clouds. But don't go down too fast. To avoid getting hit by the birds on the two lower screens, move over about an inch to the right.
Chuck D. Head
How to finish level 1:
- Swim down from start, touch all seahorses on the screen and a star will appear - grab it.
- Go down a screen, grab more seahorses until your bird symbol appears at the bottom. Swim to the surface and press the button.
- Fly one screen to the right and one screen up. Touch both clouds and a star will appear. Grab it.
- Go back to the center screen (where you changed to a bird) and then repeat step three but to the left side. Once you touch the third star you have all three pieces of the trident.
- Go back to the center screen and press the button to turn back into a dolphin. Go down the side to avoid obstacles, all the way to the bottom and touch the mermaids cage to free her and complete the round.
- Unless you touched too many octopus, enemy birds, or grey clouds, you will now have a score. YAY!
Stan
I was having trouble avoiding birds in the sky because of how your character tends to hover. Tapping the button lightly makes him flap just enough, but usually you won't be accurate all the time to get it to stay in short flaps. Therefore, make a habit of using DOWN on the joystick religiously. By quickly pressing it down you can make your bird descend just a bit to slow down his ascent. Doing it rapidly gives you more control over hovering, and thus getting the clouds. You can also use this to descend rapidly through the sky by just holding down.
