I've finished World 1 of Super Mario 2D World!
New in 1.1:
-Bomb-Ombs make a explosion sound when defeated!
-New Pumpkanos! A Pumpkano has the same AI as a Goomba but what makes it different than a Goomba is it goes at extreme speeds across the map!
-Jump on enemies to defeat them!
-You can now jump slightly higher!
What will eventually be added in 1.2:
-World 2, desert themed!
-Keyboard Multiplayer! 2nd player will play as Luigi!
-Power-Ups! (Yoshi, Super Mushroom, Fire Flower, etc.)
-King Bomb-Omb as World 2's Boss!
