Pixelization is disabled by default, you'll notice all the effect changes when you toggle between them. The v0.1.3 version tells the players in-game that they can do that from options>extras.
Yup :) I couldn't decide whether to have it on or off by default, so for now I decided to have it off. Maybe for the full version I'll have it enabled by default, but I'm still not sure about that. I'll think about it.
