I'm talking about the distortion effect where the boss is, where it kinds of distorts space around it.

I'm actually using flash, but I don't think there are that many people fluent in actionscript here, so any language is fine, I'll try to work on porting it to flash. Please explain as much as possible! Thanks.

first of all, i dont an answer
secondly to say is, there are 3 incarnations of as, so which do u use?
if you do use action script 3 (why wouldnt you?) i know that theoretically speaking there is a function to do this, but i have no clue how. may be this source code can give you a hint http://wonderfl.kayac.com/code/ea31ed4b0acfa0e6499147d5e0a62009a142a6da

Seems the Flash at wonderfl might help.  The way I would approach something like this is to divide the background (as a texture) into a grid, with each cell part of the larger texture.  Then, you can adjust the vertex coordinates of the texture render accordingly, keeping the texture coordinates the same... this will give it a wave, etc.  This stretches and squishes the texture, creating a fluid like effect.

hmm I don't think that will be too useful lol.

I think I might be able to figure out some math for a lens-like effect, and that might be enough.

This might be done by rendering the background to a texture, then distorting the texture. You could do this either by laying the texture on a dense grid and moving the vertices around (while keeping the texture coordinates the same) or by using a fragment shader to distort the texture at a certain point.

The new Pixel Bender feature included in Flash Player 10 can do all kinds of real-time bitmap filtering and effects:
