MY SUGGESTIONS:
- Different school backgrounds with different girls (all with lockers of course)
- Limited time mode (catch as many girls as you can)
- Different animations
- Unlockables and secrets ( unlockables example: catch 15 girls [prize: different background. | secrets example: catch 150 girls, and the next one you catch will have pink panties or something)
PEOPLE WOULD BE HAPPY AND MORE OF THEM WOULD DOWNLOAD YOUR GAME:
- Make the game available on multiple platforms
