This is quite certainly a bit of a novelty, with what it tries. It's actually a pretty good step-up to the previous one I reviewed from you, too.
I'll review each level, pointing out their positives and their negatives.
Plummeting Eggship - Oddly enough, for a first level, this is one of my favorites in the entire pack. It's also got an interesting concept, too - it's an escape sequence. I do like many of the sections a lot, and most of the time, you can't stop moving or else you will fall to your death. I do think that the vacuums are kind of weird, though. There are entire outdoors sections, yet those vacuums in the indoors sections lead to your doom? It's confusing.
The Crash - It's also got quite similar positives, with good level design allowing versatility and such. There's not really much to note here.
The Egg Train - Probably the one many people dislike. Oddly enough, it wasn't really that much of a problem for me. Sure, having to get back up is definitely a bit of a pain, but if you stay on the track you're probably gonna be fine.
Techno Hill...? - For differentiation I'm probably just gonna call this "Stunning Savanna," since it kind of fits the nature of the level.
Stunning Savanna - The level design here is good as well. I do like the switch to the cave theme, it has a nice transition, too. Not much else can be said for this map.
The levels here are quite a treat. There are a few problems here and there, but other than that, it's a good one.
