So I just finished playing through this, and of course, Hidden Palace Zone. Honestly I was expecting it to be only accessible via level select. When I found out (didn't really look at this thread until after I finished playing) you had to go into the Mystic Cave pit, I couldn't stop laughing to myself. I dunno whose idea that was, but it was brilliant. :v: I love all the gimmicks added to Hidden Palace; the rocket, the expanding and contracting platforms, water geysers, maces. Even some areas of the layout remind me of the old screenshots (mock ups I think?) from way back. I was a bit confused why the layout didn't start like the S2B Hidden Palace, but you didn't leave me disappointed (it came in later). The design and architecture of the stage is really great, it helps keep Hidden Palaces layout unique from the other zones (those are some good looking loops!). Makes me wish I could see a full map of the stage though. With all the special features that Sonic CD, 1 and 2 have had, it makes me wonder how you can even top this if a Sonic 3K iOS port were to be done. There isn't much to "restore" there.
