In celebration of the 25th, I have crafted 25 mini-levels to jump through!
I went waaaay overtime on this.
MMF2 has really lousy performance when it comes to rotating/scaling sprites in software rendering.
Hold Shift to jump higher, and to bounce higher off the note blocks.
Don't leave any edge of the screen.
Don't hit any Spinies.
Grab the Super Mushroom. If there are coins, grab them first. Then the Super Mushroom will appear.
You can bounce upward off the top corners of the note blocks.
You can go to any number level by typing that number into the File -> Password dialog.
The "Ow, that really huuurht!" voice clip was by Malefact. Sorry.
Edit: You might want to install the "Arcade" font to play this, but it's totally optional.
