For those getting the white screen you need to install unity on firefox and enable it by clicking the lego button near the top left of the screen. That being said I had to put in a missing achievement for the flawless. I did it several times (after far too long of trying!) and it never gave me credit. This game is silly fun.
Can't play in Chrome so I opened it up in firefox.... doesn't play in firefox. Got desperate and tried explorer... still nothing.
You must require magic and wizardry to get the BOTD... I am not worthy it seems.
Okay so I spent literal hours playing this game (which I really don't like by the way). Once you unlock the flamethrower the game is easy mode. I found it's much easier to shoot behind you and the game won't lag as much. The car is a waste of time and tends to make more zombies appear on screen and my BEST advice is to ignore the antiodes until you get the flamethower and then replace.
Once I got that the game was more easy mode and I ended up getting the hard badge, because frankly at that point I felt committed. XD If the kongpanion wasn't on this game, I would have given up at the easy badge.
This game makes me want to rage SO much. Terrible game of the day and the scoring system is horrible. It goes from easy to impossible. Yeah maybe it would be easier with a flame thrower but I can't get that far in the game!!!
