no go on FF3.6 w./ 64-bit flash
Same problem as ZeoX69. Nobody takes damage, not even ice blocks. Flashplayer 64-bit linux alpha, version 10,0,32,18 -- running in firefox 3.6. Upgraded to 10.0.45.2 -- still same problem.

Runs fine in Konqueror on the same computer with the same 64-bit plugin... Sometimes doesn't throw when I click, but otherwise fun.
