Ok, you know what? You've named this incorrectly. It's not Dash's World, it's Shuffle's, JTE's, Flame's (and Turtleman's) and STJr's world with a little bit of Dash put in. Most of the stuff in here is from other mods and don't give me that "It's hard to port" BS because it's not, I've ported code from other mods before and it's very easy indeed and requires little to no modification of the code in question. That is, if the version is around the same (SPMoves is rather hard to port to 1.09.4, I presume) which it is.
I acknowledge that you have given credit and I respect that, but the point still stands, this seems more like a compilation of features from other mods with a bit of your own stuff thrown in than anything else.
And just for the record, a lot of those new textures look horrible, especially the grass texture. They reek of the 'brown == real' theory, which is not a good thing. By the way, who did the gems? SMS? =P
One more thing...
You want to go from modifying SRB2 code in little bits, to a game from scratch? You are kidding, right?
Ok, I lied, there's one more thing as well...
The slopes code in SRB2 hasn't been touched in hundreds of revisions, it's not in 1.09.4 for a reason.
