Stardust Prison Break

You are a meteor trapped in an alien prison that generates energy from your collisions with the walls. The aliens have left a small opening for you to leave so that:

1. The meteor stays motivated to keep moving in the hopes of escape.

2. They think a meteor dumb enough to get caught can't possibly escape the prison, even with a clear opening. 

Prove them wrong!!! 

Controls:

W - Move forward

A/D - Turn left/right

Rules:

Bounce of the walls to get more energy.

Get the minimum energy to break out of the prison.
