Press space to begin (you can do this even if you've already died). You are the triangle. Avoid walls. A / left arrow ==> Spin counterclockwise D / right arrow ==> Spin clockwise If, when you press space, it goes really fast from the start, press the green flag again.
I thought the original project was a little too easy, so I've basically doubled the speed of the obstacles and made the player's movement speed 1.5x faster. Good luck.
