Nightmare starts at level 11 – Tower Defense Zone 2 Review

As I wrote, nightmare starts at level 11 it's really hard to advance. Actually there is a hellfire mode on each towers however it is really hard to beat the wave 21/25 on lvl 11. I've played 30 times already for lvl 11 but I still can't figure out for win at lvl 11. Looking for strategy in my head. But obviously fun! It looks like playing Dark Soul. Die all the time but I found myself playing it.
