Warning: Don’t play this game if you’re planning to get something done in the following few days.

AntBuster

One of the recent Tower Defense games: set and upgrade towers to prevent ants from stealing you pizza I managed to get to 64th level and scored about 11k points, so.. beat that

Only wasted about 6 hours on this one, not much compared to the 3 days I played another tower defense game I found about a month ago.

ughh is there some firefox extension that blocks addictive games?

Now back to work, got a bunch of stuff to do for today.

edit: played some more, got to 72th level with ice cannons and rocket launchers, 14425 points!
