Very nice Update!
my second try resulted in my first loose... which was really exciting and made me focus on the next run even more.
The Trick to getting the high numbers is to focus all energy on reducing darknes speed first (Tower of light and lighthouse(can be build after you build docks)) and then use both ways to push back the darkness
My Bosses just self destructed?!?
also everytime you unlock a hero you'll heal completely so if you unlock the next character when you reach one heart you'll have a total of 15!!! hearts!!!
Hiding in shadows is the key ability here. Also notice which way the nearby guard is looking.
