Verity - I've had this problem on Firefox on college campus computers. Might just me a setting's issue. I use Chrome at home personally and everything works fine.
After 3 hours of trying - Finally hit 2000 kills. Oh look, 5 bullets left? Ok, lets see how far this goes... hmm... reaching 3000, one bullet left... let's kill that gold maker and be done with this. Final score... 5500... Where was this streak the first many times when I was trying for 2000???
why do the spear guys become stupid starting the level before the giants? Suddenly they'll just stand still while enemies are approaching, or let themselves get pushed back without doing any damage or throwing their spears...
