I was wondering if anybody has any hints or a walkthrough for it? I cant even beat medium and only level 80 on 10k which makes me think it must be impossible to beat hard with 100 levels and not 10k and 50% more health. Everybody comments saying its easy but im sure they only did easy and did 10k for 5 minutes and got bored cuz its so easy at the beggining but impossible at the end. Makes me feel stupid cuz i spend so many hours trying it and failing!
