the lag has been significantly reduced, and the end game danger zone shrinking the safe zone is highly effective.
i would recommend trying to make the usernames invisible when a user is under a tree, so they get the same protection as someone with no user name. or you can give people with no username the default username of anonymous to make it fair. but this will just incentive people to make there username, ".", so they are more hidden when under a tree.
keep up the good work!
