Advance Math Game

Hii everyone I've Developed a Math game which offers following features:

• Basic Math(Addition, Subtract, Multiply, Division, Mixed)
• Advance Math(Fraction, Roots, Algebra, etc.) I'm improving them,
• Level based game (each above category is level based which will increase difficulties
• In Game Rewards,
• Stats(Total questions, Accuracy, Average time) etc.
• 2 Player Mode

I'm working on Major update with following features:

• Stats for each category,
• Achievements and Title for every category
• Avatars etc.

But I'm not getting any download other than my some friends and I didn't get any feedback as well what I need to improve. Please Help Me to get some download.
