SMB Mode

Effects

 * Rocks now have a chance of being replaced by "? Blocks". Blowing them up spawns 3-10 coins
 * "? Blocks" also have a 1% chance of spawning Mario-Themed items, such as Mini Mush, Magic Mush, 1-Up and Turtle Shell
 * If you get 99 coins, the next one you pick up will give you a 1-Up and set you coin count to 0 (or to 4 if you pick up a nickel, and 9 for a dime)
