Me too. Lag is Really really severe. But in flash version (offline)I can play it somehow.

Moving actors are like 12. Static actors like trees are more than 20. Yeah I suspect it is the handler that causes the problem. There are countless region in the game so that when hero tank enters, it will shift to another handler something like this:
There are two regions in a single enemy: Vertical and Horizontal.
This the handler:
when Hero tank enters vertical region,
if enemy idle handler is turned on, turn it off.
set agitated handler to on.
when Hero tank leaves region.
set agitated handler to off.
set idle handler to on.
every n seconds:
if idle handler boolean is on, trigger event idle handler
every n seconds:
if agitated handler boolean is on, trigger event handler
none of them are disabled. but can only be triggered through n seconds if boolean is enabled.
for the continuous collision, I am still in the process of investigating... man this is driving me nuts.
If you can figure this out, I really appreciate it... and I know you could.
