Does having 0% sleep on hardmode eff up your fighting? Because my character starts doing random stuff and freezing up in the middle of fights! Haha I thought at 0 he'd just fall asleep on the floor but I love this if it was intentional!
I usually hate td games but the play-style and charm of this one has me hooked! I just love the voices and commanding my own soldiers rather than the boringness of some mechanized tower. This game has life.
To get the hard badge you need to focus on getting that multiplier up. Which is actually easier than you think. In the beginning just make really small hills quickly like a half inch and before every gate make a little jump so you buzz it. That gets your multiplier up really fast! And can easily get you up to 40x without any tunnels. As you start to get too fast to buzz... Just do what you would normally do. Hope I helped! Plus up if it helped you!
