Really love the use of the theme here, very creative :). I feel like it could really use music, a background, and more detailed artwork across the game though. The fish also moves very quickly vertically, but at a snail's pace laterally. I lost the patience to get all the way through the game but it would be a lot better if the fish's vertical and lateral movement was more balanced. Nice entry :)

This is so creative, I love that the map is the shark's mouth I would never have been able to come up with that! Also one of the best uses of the theme, excellent job (:

With a mouth like this, just imagine what a bite mark from this dude looks like in an sandwich! I know I sure imagine it...

The only thing I think could be improved is that maybe the last few levels could have another mechanic  or something added to them to keep things fresh, but dang I really like how creative this game is already

Ah, a quite literal take on the symbiosis theme:
