So if you've watched Ceave Gaming you might notice that the icicles are global ground. Sadly, this does not work anymore. Nintendo has removed the fact that icicles are GLOBAL GROUND. Basically, that means that you can't remake Blinking Blocks, right? Guess what? WRONG! It turns out global ground is still alive, but in the form of Snake Blocks. While this DOES make the timing much more limited, it's good for remaking Blinking Blocks and such. Not only that but it seems to work for Super Mario 3D World two! Now you can continue this amazing inventions... AS LONG AS ONE OF YOU DON'T TELL THIS TO NINTENDO!!!
I'm just posting this if your invention got screwed up by Nintendo's patches removing global ground in Super Mario Maker 2. Thanks for reading.
