xboxdrv: I've added a bug to the database for this, we use SDL and so it "should just work" but nothing in software does as it's told! Thanks for reporting that.
The next release should fix the issue with the spider camera shake, good spot.
We prototyped an "intelligent" camera and it wasn't very successful. Because the player is pushing right-stick to the right, the camera swings behind the player a little, but the direction the player character faces is relative to the camera so the player character turns a little and the camera swing around a litte and on and on. We can dampen that but players reported that they started to feel a little sea sick as the camera never stopped sloshing about.
In the end we designed the game around the eight angles that you can fix the camera at but I agree it was a compromise and we're trying to balance a lot of things for the player.
The depth of field blur, yeah we can adjust that. It should give a sense of depth not simulate being tipsy.
