Hi there.

1.)Yes, I think there is a way. I will get back to you on this, after I finish getting a nice 'black and white' shader done, currently using just 2 colors doesn't quite look right.

You can do with colors basically whatever you like, I think the main solution to your problem is first tone down the overal brightness of the colors and áfter that apply the bloom blur. I promise i'll try to 'fix' this shader this afternoon.

2.)I will look into this too, although it seems to be present indeed, it's hardly noticable with my projects. Your projects are 1024x768 too?

Cheers
