I think this hack has loads of potential, but there are somethings you should really work on.
For instance; the the storyline. No kid will suddenly be offered a job at the Police. Make an reason behind it if you haven't done so. Make the dialogue's more realistic, try to make the civilians more respectful, and make some scyinical cause you are a kid after all.
And a question;
Will you have to complete some side quests? You are an officer after all.
You can't only focus on getting Team Rocket when there are civilians in need of your help, can you?
