Not bad, especially for a demo!
I just have to say what everyone else said about it, but I also got information, first of all!
"Yes I know the text is going a little slow.... but hey.. it's meant for kids too!!" I learned about this site when I was 10, and I could read so much faster than that! Kids don't go on this site!
Now, make the dialouge about 3x faster.
Make the egg throwing part easier! I hit someone with a full charged egg and it did nothing! Especially don't make the red shy guys go that fast, and maybe there's a glitch unknown to you that sometimes when you throw the egg it doesn't hit someone. Get some music for the menu screen I guess, maybe the menu screen for the game if you can find it. Get a skip button for when the enemy talks to you, and maybe get a couple of auto saves so when we load up we can get right back to dieing at the egg part. Good luck, and good job drawing the characters similar to the game, they look great.
