ShellShock – a Bash 3 / Bash 4 spaceshooter!

My weekend project: A top-down space shooter in Bash
Note: Bash is SLOW. This requires an Intel Core Solo or better to run well.
Comments welcome. Patches twice as welcome.

Update:

Since the name “ShellShock” was used as a nickname for a Bash exploit, this game has received a whole lot of attention. I even got a patch!

Security wizard and generally awesome person Mikko Hypponen of F-Secure recently tweeted about it, and it even made the front page of digi.no. Here are some pictures.
