This is incredible! The core gameplay concept is surprisingly nuanced. Even when I thought I'd broken it with infinite coins and overlapping buildings, the constantly changing buildings and characters combined with the balance between under- and over-population made the game challenging for way longer than I thought.
Sure, switching between orcs, farmers, and guards is simple, but the fact that guards attack orcs means that converting a horde of orcs can be really risky if too much of your army is attacking them. And if all three types are in the same area, there's no way to remove the orcs. Orcs attacking towers turn into farmers harvesting from trees. Just super interesting, this game works really well!
