Crappy controls
Controls were pure shit and took away from everything. Upgrade the people graphics so I know that they are people before I accidentally hit one and find out that they are people. Graphics for everything else is good.
I liked the destructible environment and enjoyed hitting the porta potty for a shitsplosion.
Fix the controls and add a lot more redrawn people and you get a fun game, but make the goal 80% of the people or something like that as it isn't fun driving around trying to find that last guy standing between some trees that you keep hitting.
