Welcome to ASTROBLASTO!

How to play:
L/R arrow keys rotate your ship, up thrusts, space bar fires

thread 'main' panicked at 'sample rate could not be set: "Invalid argument"', libcore/result.rs:945:5
note: Run with `RUST_BACKTRACE=1` for a backtrace.

I think this is due to an issue in rodio, that was fixed in 0.7.
Updating the dependency should fix the problem.
