W A S D to Move

I've been working on this game in my spare time for about 6 months now. I'm not a professional game designer but I've put a lot of time into this game and in my opinion it is quite good! In this game you go against different opponents in each level with the controls starting at W A S D. After each level the control change 1 button to the left ex)W A S D ---> E S D F.
