This game is very frustrating. However if you can make it to level six, you get the flamethrower which makes you pretty much invincible. The game went from crazy hard to trivially easy with this one weapon.
The badge is actually one of the easiest ever. The challenge is getting the game to load. Apparently the domain name, www.gimme5games.com, doesn't resolve properly so add the line "216.104.46.66 www.gimme5games.com" to your /etc/hosts file to get the game to load. Someone posted this earlier this morning and that was how I got the IP address.
