I like the mood of this, and the graphics for the fish are interesting how they are only partly visible in the dark. I made it down to around 200000m before my fingers got tired! Is there an ending?

@khaotom Thanks, I thought of something special for the end, but there wasn't time so it's endless for now.

I think this excels the most in creating a very eerie mood/atmosphere between the stark lack of music, ambient sound, and the fact that anything resembling a 'real' looking fish stops pretty quickly to be an incomprehensible assortment of colorful lines. It evokes a certain surreal quality to it. Add in a bit more of a concrete end-game goal and I can see this being a lovely little presentation piece. Well done!

:O Love the originality on this one, even if the ocean was one of the most used themes, it feels creepy and the atmosphere is dark and muddy. Good use of the underwater audio and simple art.
