Tip: You can use Lunar Magic's Overworld Layer 3 Editing system to edit or create your own layer 3 images (castle bricks, fish, rocks) and apply unique effects per level via the Layer 3 Bypass in the main editor.
Unlike other blocks in the blocks section, this one is much better:
-No wall-clipping and dying
-regardless of how many collision points is touching each part of the wind block will not "combine" and pushes Mario faster (this happens if you have the block itself increments or decrements Mario's position).
@Ruiyabi: I don't know, why you use BTSD even though it's obsolete but if you delete the line with "print" at the blocks then you can insert it with BTSD especially because it doesn't use anything Asar related. (Don't forget that it requires UberASM too!)..
