this is pretty awful...
after you pick up the first guy's gun, you cannot shoot it while walking, making it impossible to chase him down and shoot him. also, it is so horribly impossible to try to jump over his "afroball" form that i was actually cursing out loud every time he mowed me down. I got to the puzzle and couldnt finish it, so i continued. Just like everyone else, i couldnt kill the second boss after continue bc of a bug. he simply wont die...and also he doesnt shoot missles any longer. anyway, at that point i gave up bc this was NOT worth refreshing the page and trying again.
