Ummm....
Well, size-wise, it takes up around 9.7 kilobytes for the big level, since it has to have 3 pictures for 4-lvl grayscale. The other two solid and kill pictures take up around 3.2 kilobytes (I'm talking about a 200x128 pixel level).

methinks that 200*128 should be about right for level sizes... not too big and not too small

and I'll get to work on another level as soon as I have the time.

So could some other people help with the levels? please??

I would want to, but I need to work on my exams and I know that would probably steal a lot of my time.
I hope there are others who can help.

Thanks for saying so.
Yeah, hopefully others can help.

... Wow.
Well actually, each level (If 200x128) takes up about 16.1 Kilobytes. But of course, some levels will be smaller, and some bigger.

If all levels were 200x128, I could fit in about 6 levels.

EDIT: So each pixel in the picture takes up about 0.126 bytes.

Compression? I have no idea...
But it is cool because the NXT uses .ric as a picture. There are some easy-to-use .ric editors out there. The file can actually get pretty advanced. It can have all sorts of stuff like varmaps, different copybits, etc.

Ok. Well it's probably hard to check using an iPod/playstation 3.
So hopefully some people can help make levels.

So.... does anybody happen to have any freetime for this? I know, i'm so impatient, but I really need some cool levels.

Wow, that's nice. Thanks!!
