For now the shader can't be turned off. You have to bug the project lead over and over until they will force me to turn it off. They'll make the call. Scrolling will be enabled once an actual level is completed. We are not going to make the same mistake as before, releasing a demo without any "graphics". We lost a lot of interest from it The spring, as well as the solid blocks have that disadvantage in the original game as well. In Sonic Advance 1, it was changed, and we all know what happened in Sonic Advance 2 (no solids at all). I'll know how to fix it, but I haven't tested what results it could lead to in the long run. EDIT: Now there has been an update to the release package. Read the first post.
