I tried playing the updated version, but without success. Around week 5, they start overwhelming you with purple and brown units. You can defeat one, but the second one is impossible to beat. The brown Goshak (level 25, 24 attack, powerful ballista) attacks even the castle where my main hero (level 14) can't put up any resistance. Resources are still scarce, and this significantly diminishes the enjoyment of the game.
