GENERATIONAL level pack in my opinion. There's so much to talk about but lets start from the top with the good!
My god the flow for all the levels is amazing, the feel and focus on momentum gain through rolls and spindashing reminded me of sonic GT in a lot of ways but with a more platforming-heavy approach. REALLY love this as it's what I've always wanted to see in mappers, mixing the horizontal speedbased sections with verticality without ruining either is a fine line and this mappack manages to teeter on it perfectly!
The bosses are so goddamn flashy, cool-factor is pushed to the forefront and it really shows. I love the chaos of them, though it can get a bit cluttered when in phase 2 of some bosses. The parry is also much more forgiving now which makes the bosses far, far more enjoyable rather than button-spam fest 10000.
Bringing mach speed back but refining it like project 06 was visionary stuff, same for bringing in skydiving, genuinely amazing concepts and execution (even if some of the mach speed sections absolutely destroyed me).
Now for the parts I was dreading discussing... The levels feel very... flat, decoration work is kind of lacking and the lack of lightblocks and other effects makes a lot of the death pits and skyboxes feel empty and rudimentary. This gets rectified to an extent right after the third boss fight who I REFUSE to name on principle, but shapes and stuff could be more complex. Maybe something to look forward to in a sequel mappack!
Overall, I'd give this a 10/10 if I could but there are still flaws here to iron out, so I give it a 9/10, once again, absolutely amazing.
