This is a pretty good recreation/showcase! I was expecting there to be very little but I was surprised with the amount of detail and the whole lower part of the map. Along with looking good, it also has some good screenshot potential. (And I normally don't go around taking scenic screenshots.)
There are some minor flaws though. They don't ruin the pack but I would want to point some out.
One of them being it's kinda hard to come to pack to the initial spawn point since I have a 50/50 chance of actually reaching there with the springs. But that might be due to the fact I played the stage with a mod character.
Another is that it feels just a tad bit empty, especially in the lower part. Some lanterns, flowers, and general decoration might liven things up. Maybe even hide some Chaos Emeralds so players have a reason to explore outside of finding the secret room and such. This leads to my final point.
The secret area just kinda blends in. If I didn't slow down to see the cracked wall I would have just kept running by it. I know it's supposed to be a secret (kinda). Maybe if it was pointed out a bit more it would be easier to find.
But besides that, great job! Can't wait to see more!
