"Deeper than the Abyss"? "The source of the light"?

[Jekyll Grim Payne]

I just wondered, whether these phrases here were a hint about Aquaria 2, or there actually are places much higher and much deeper?.. I wouldn't like spend hours searching of there actually is nothing else. I only know about a boss in the Abyss I didn't kill, as it was too tough, I suppose there are a couple of easter eggs, but are there really big secret places or anything?

There are quite a few other areas, although you need different forms to access them.
Have you been to Mithalas City? That's a start for getting you "the source of the light."

[Jekyll Grim Payne]

You got me wrong. I've beaten the game already and I got all the forms. Do the words I quoted simply refer to the Body and the surface, or is there something else? Like that boss in the Abyss. Don't remember what it is already, but it was strong, I wonder what I could get from it... also, I got only two pets of four. And by far not all the recipes. In the ending sequence Naija referred to something that I, kind of, haven't yet discovered: is that supposed to mean "there will be a sequel", or I missed something? I even heard about an alternative ending... But I haven't found any description of easter eggs, secrets, etc.

You need to collect all 3 of her lost memories, then you'll get the full ending.

This full ending then leaves some room for a possible sequel, but that doesn't mean a sequel is actually going to happen.

If you've collected all 3 lost memories, the game will show a message that the other ending has been unlocked. in the final ending, you will be given back control over Naija after defeating the final boss, and you must swim in a spiral towards the middle, where she will have a final confrontation with the shadowy figure Mia.

One memory is in Mithalas city, you'll get it once you've found the kitchen there.

One memory is in the giant water bubble above the sun temple, you'll need to go through the sun temple to the top to get it (not via the sun worm, but by jumping from gear to gear)

one memory is in the Abyss, you'll need to drag the pearl out of the whale and into the pearl holder more towards the ceiling of the middle room in the abyss.

[Jekyll Grim Payne]

Aha! That's intriguing. I remember that bubble and I think I remember the one in Mithalas. I guess I haven't found the whale... Well, I downloaded the treasure hunter's map, so I'll make it.

The other thing I'd like to know is: is there a changelog that explains the difference between 1.1.1 and 1.0.3 versions of the game?
