While I'm not a big fan of cbliss and some of the textures selected, It's a nice combination of stages, I've already extracted the Shadow Moses Island: CE and the Port City Aero Dive: CE for my own custom pack. I might take a few others after some extra time on it. All in all, nice work on this.
I noticed that while there are images in place on the stage-random screen, there are no larger images that display when you've selected something. It isn't a big deal, but it might be a little jarring to see a small picture of Grasslands and a wider image of Big Blue displaying. I need to correct this in my own custom pack as well.
Another question I wanted to ask, Is the Summit in this pack actually a smaller stage than the Summit PM that was already out there?
Also, is it possible to make the ledge/wall more pronounced in Flat Zone: Kitchen? It seems kind of blended in with the stuff that's already positioned to the side and feels a tad jarring when walking off it. I'm sure it can be gotten used to, it's just a tad deceiving. Just my two cents.
I'm sure I'll pop back in here to see how things go. Overall, nice job guys.
