I used to able to beat hard without too much difficulty, I cant even get close to beating it now, not sure what else they changed other than the ice tower but something is much much harder
I have location turned off, it never asked me for my location/told me I need to turn it on for it to work. The graphics aren't the greatest, it lags a bit at times. It's fixed path, and there's only three paths. Easy, medium, and hard. All that being said, I think it's worth downloading. It's hard after a while, and sometimes I like playing fixed path instead of sandbox. So it nicely counters fieldrunners. Hoping for an update soon.
