Had fun once I could get past killing the first tower - there should be some kind of fail-safe to allow a player to recover if they send all their troops out and lose, especially with 0$ starting capital and no way to gain it other than winning battles. Otherwise the player is soft-locked and can't progress (of maybe I'm just missing a mechanic?)
But I do love the little sounds effects and music, and I like the way that things scaled up after you "took over a region"
