I'm fine if it's more difficult without a partner, as long as the later levels are still beatable. I'm hoping it doesn't suffer from the problem/feature that started to creep into Orcs Must Die 2 where some levels are designed specifically to take advantage of having a second character (making you guard 4-6 separate paths rather than 2-3).
I know it's designed for co-op, but is it feasible to play solo?
