Simple Platformer

This is a very basic platformer game I made for practice.

The controls are:
W & D for left and right movement
Spacebar for jumping

Your goal is to reach the white platform at the top right of the screen.
The game is an infinite loop that can be played over and over again, and keeps tracks of wins and losses.
You'll have 50 seconds to complete the level before it counts as  a death.
