I wrote my player code.

I'm proud of getting my player decided.
I'm stuck on trying to make the circle fall and increasing there speed.
So, far I have no new interest or idea.

+#Game Proposal
+
+##Team
+I am working individually on this project.
+
+#Game Overview
+Title: Dodge
+Vision: Players dodge the circle's and more scores they get the more faster the circle's start falling making it fun to play.
+Appearance: The game would be inside a rectangle shaped box with circles inside falling from the top.
+Interaction: Players will use left and right arrows to avoid the falling circles.
+
+#Core Mechanics
+1. Left and right arrows
+2. Circles falling from the top
+3. If a circle hits the players, the game ends.
+
+#Milestone
+Create the rectangle board with a player that can move to dodge the falling circles.
+
+#Challeneges
+I think the most challenging part would be to increase the speed of the circles falling from the top.
