This is a toxic variant of the Timed Lift (Sprite BA), which can hurt or kill Mario. You can customize the time it lasts for (1-9 seconds), the X and Y speeds, and toggle additional behaviours, all with the extra bytes. There are also defines in the .asm file that let you change the palette and tiles used.
By default, the .asm and custom sprite list are preset to meet the specifications of the request. See the .asm file for customization options.
Everything works nicely, so accepted. A couple things to note that may be nonobvious:
- This won't display the time remaining by default (by way of being a request fulfillment). You'll need to set that in the .asm file and use use the supplied ExGfx if desired.
- One "second" is really 64 frames (slightly longer than a real second).
- If configured to make Yoshi run away upon contact, he'll do so even if Mario has a star, which may be unexpected.
