I agree with Mezec. The reverse is crap, the car should turn in the CLOCKWISE direction when pressing LEFT, it's too damn confusing when the car doesn't act the way it should.
10 : Get Out, 19 Green Light, Red Light, 20 : Fully Loaded and 21 Ping do not work for me. Even when I looked at the walkthroughs on youtube to make sure that I was getting it right, was doing exactly what the video said, and still it does not work. I can do pong, but ping does not register. The green light on 19 never changes size. Fully loaded never goes beyond 1 bar. Too buggy! 2/5, but worth a 4/5 if the bugs are solved.
Needs to be updated to make multi-placement of defenses easier. Clicking on the defence, then clicking where you want it, then having to go back and clicking on the defense has caused me to let the creeps escape.
Easiest way to get the CTF challange without even trying? Just stock up on 49 gunmen, they mow down the enemy without you even doing anything. I'm up to 2 mins so far and still I haven't needed to take a single shot yet.
Also, the damage tables are messed up, for some reason I am now unable to hurt the same enemies on the same level after I died. I do 6 damage instead of my previous 10-15+.
