Marble Zone. Probably everyone's least favorite level in the original Sonic the Hedgehog game; if someone says otherwise they're just being contrarian for the sake of Reddit points or something. This level was total garbage in the original game and here... good god where do we even begin?
It's SLOW. Like, *real slow*. Marble Zone is filled with all sorts of moving platforms and spike traps and if this game was struggling with popping four item monitors in Green Hill Zone then we're about to see this game try and push a boulder up a mountain. Every movement in this level feels like it takes an eternity to accomplish.
Block physics are completely broken. You can push a "floating" block into lava... and then inadvertently push it the other direction if you fall off and take damage and struggle to get back onto the block. There are things that are messed up here that aren't even do-able in the original game. Also, hazards and moving platforms tend to just "pop" in and enemies do the same and wind up getting stuck INSIDE of item boxes.
