1. Art
For everyone who has issues with the art. I know its pretty bad and I made a note about it in the developer notes section.
NOTE: The art is very rough right now, I plan to redo basically everything. I'm pushing this current build to see if there's any interest in the idea, the fairy odd parents universe, and characters before commiting more time and effort...
I was planning to redo the art a bit later, but since it seems like the biggest issue. I'll try to make some half decent art for the next release.
2. Android and iOS versions
At this time I'm not planning on supporting android or iOS. If there's enough demand for it, I'll consider doing test builds for both of them and going from there.
3. Other Characters
I do plan to add all other major characters (Vicky included for the person who asked).
4. Will all the characters have the same figure
No, there will be variety I just made a bad call using mostly the same figure for the current set of characters.
