The revenge of the curse of the galactic empire - 2d space shooter, cross-platform?

Hello,
This is my first finished project! It is written in Java using slick and lwjgl. It works as an applet, so You can play it in Your browser on windows/linux/macos/solaris withouth any issues (hopefully..).
The game features an online leaderboard in which everyone can participate without any costs(You just need to register to do so).
After meeting certain criteria You can unlock hidden weapons and modes (You get the first one after killing 5 of the colorful "snakes"). I tried to make all weapons equal in their value, so, although each one works completely different, there are uses for all of them (for instance some are better in the early game, some in the late game).
You can find info about the game (video, or just play the game) on my website http://hugeowl.com. I would be grateful for any feedback, especially related to cross-platform issues, I cannot easily test whether there are problems with the game on OSs other than windows.
Cheers,
Bartosz

Slick is a lot of fun, No problems on 32 bit Ubuntu Linux 10.10

except the lack of dvorak friendliness :P It's impossible to play with wasd on a dvorak keyboard. Option to change key binding is always a nice feature.
