Poor Molly... 1. No changing sprites, You're only able to change yours. But you can add more dialogue to other characters, But you can't change the dialogue. 2. Don't change the background music but you can change the background (No seriously, I can't think what to do for the background) 3. You can move/shrink the other sprites is you're running out of room. 4. Eeh, Nothing else, I guess.
I've added Molly, Sunshine, Kirby and... wait WHO IS THAT? (okay its probably going to be very predictable tho.) Molly: HAHAHA, Ah- HELP ME PLEASE! >_< Sunshine: ... (What to do? ._.''' ) Kirby: Poyo. <(-'.'-)> ???: Hehe, It worked. I better hide. >:3 (BTW 'Mol'y' was not a spelling mistake, Its just Kirby saying but didn't quite get it right since he can't talk that well)
