gouessej,
Try manually putting the native files for your OS to make it work.
I can do it but a casual gamer (not a coder) would not accept to do it and more than 8% desktop computers use Mac OS (about 1% use Linux

). The JAR is provided (FuzzyMain.jar), it would not be difficult to use an applet or Java Web Start, sign all JARs with the same certificate, just add one line into the JNLP file to load LWJGL and one line per JAR (some libraries are in /lib inside the ZIP file). If the author does not like applets and Web Start, he can use GetDown, NetX, IzPack or any other cross-platform installer. I expect from a Java game to work on the major families of operating system, not only Windows

Nice little game! I found level select a bit confusing (see above 2 posts), otherwise it was pretty straightforward. Also, the collision seems odd, e.g. if I touch a crawling slime thing from the right side, it doesn't hurt me.
Here's a linux version for others to try. Execute the 'run' file from the terminal (tested with ubuntu 10.04 / sun-java-6):

Thank you. I'm going to test it immediately.
Edit.: The Linux version works fine (only on 64 bits machine). It is nice to hear than OpenAL just works fine

The game is nice and fluid, I played with it a few minutes, this is a good base for a larger platformer.
