70 - 100 kills max before, suddenly i have the badge. 350+ kills. Ammo is the real problem. Basic weapon infinite ammo is great idea.For the badge,all you need is to fine decent top platform, and get as much ammo as you can buy keeping enemies off. From there on, all is fun part. Stick to gauss, or supershotgun? and you'll get to 300 in no time. Game really need few minor improvements, of which most impotant is key binds for weapons.
I really don't like to scroll 2-3 seconds to get to shotgun,which gets really loaded at some time, when i run out of gauss amunition, or so. I used to think this is going to be one impossible badge, but now i am really happy to see that yellowish line around it in my precious bagde collection. Great game, anyway.
believe it or not, game is not as 50% luck. keep it small, keep it spiked, and when you are expecting balls to come down, just don't be horizontal, you must drop the balls as soon as they get. so narrow the paddle and highscore is yours.
It's really entertaining game, a pleasure to play.. but not too challenging as i expected. need improvements considering that.. 20 more levels, maybe? and less lines?!? i finished few with 2 or 3 lines to spare..
