Alright, so I picked up and played it. And man, I was VERY disappointed. Let's delve into this, shall we?
So first off, the new Jade Hill is a snore. It is boring, bland, and uninspired. It simply isn't good my any stretch of the imagination. It's just boring, strait up. It is also not very pleasant to LOOK at either. The GOOD old Jade Hill Act 1 was replaced with THIS? As for Act 3, the boss is an even BIGGER snore, because the arena is so HUGE. He flies all the way to the other side. There's a REASON why GFZ3 was so small. Add to it, Tunes 12 is a terrible (and terribly looped) boss tune. And for Hidden Forest, it's clear you have no idea how to use that flat right (fake floors, invisible solid FOF with that bounce trait, IIRC), and those 2D segments were lame and unneeded.
As for the archives, they're borked; they're ALL forceskin Sonic, and it's best to just move them out of the SRB1 Remake slots, and Old Jade Hill Act 2 plays no music. The match stages are HORRIBLY huge, and the weapon panels are far too plentiful, while AMMO is low, as well as the Ring count, which is FAR more needed. They also use HORRENDOUSLY looped music. I changed those tracks the second I herd 'em. And the circuit stages are the most bland, boring, and unneeded stages I have ever seen; they're total snorefests, and they just shouldn't be there. get rid of 'em pronto. Infact, just stop with Match too. Just focus on SP, because these Match/CTF levels are BY FAR the worst things in the pack. I swear, this whole pack is pretty dang vanilla to be honest. There is just NOTHING interesting here.
