I updated (it still 0.0.3) the applet, it should work fine with the mouse now.
I still have a nice black square over the cursor on MAC… but the game is as playable as on Ubuntu (at least on vmware).
Be sure to clean the Java cache, because (on Ubuntu) Java kept the cache, even I changed the JAR (I will search how to avoid that)
@gouessej : So, what are the main differences with OpenJDK in applet mode (in order to make it work nicely) (we can talk by PM)
I really would like to make it work everywhere, even if I have to changes something in my code (I’m seeking for the maximum portability with as much features as possible).
