You can also make yourself permanently invincible, attack 10 times per second, and teleport around, if you get a reference to some of the internal variables. I actually found it quite difficult to get that reference since the project uses requireJS and doesn't leave any global/window references. As far as I can tell, the only way is to pause in the debugger, which is much more tamper resistant than I expected it to be.
