Yes, I'd say please try making the character. The more ideas we have to choose from, the better, and right now we have none

As for cloning the level geometry using sprites: My art example uses the exact same method. Problem I'm having right now: how do you place it in the level? Drawing the thing and then adjusting the level geometry to it is rather a pain because WED doesn't show the contents of sprites, only rectangles... or am I wrong?

We could get screenshots of the level geometry and then draw on those screenshots, but that's a long process as well, depending on how many levels we make.
I'm thinking about a way to code it: if you have a transparent image maybe we could make 3dgs place blocks (map entities) wherever the image is not transparent... that sort of thing...
