Fantasitc game, but if your zooming in at all it offsets the image and makes it near impossible to complete the hard badge. Just reload the game (make sure your zoom is at 100% for any browser) and it'll correct itself.
I'm quite impressed i didn't encounter a lick of lag, especially with the immense amount of bullets just...just everywhere. Way to be awesome Mr. Kupo.
If anyone wishes to play easy mode (that still is kinda difficult) change your mouse settings so right click is double click, spam that to gain machine gun.
YES!!! Getting the hard badge was totally worth the Grand feeling of accomplishment, especially when it seems everything in the world is doing it's absolute best to prevent you from completing it...now excuse me as I go smash some flies into a mushy paste....
