Bug report: Enemi should be spelled Enemy.
Also too many alert boxes.
Maybe add a progress bar for experience.
Maybe add attacks left(have to use potion or go to PokeCenter to refresh attacks if they are out).
Didn't test your game yet, but I will as soon as I get a computer with my phone's drivers on it ^^
One remark, do you have the right to use the Pokemon name and pictures in your game ? That could end in legal issues if not, and I don't think you'd want that ^^
