KULE: The Undying Hearth

You hold while the Undying Hearth still burns. KULE is a tower defense game spanning three ages, from stone axes to tesla coils. 120 hand-built levels, 17 tower families and 17 enemy mechanics are connected by real placement, real range and real pathing. FREE PLACEMENT No fixed slots. You raise a tower anywhere along the road, and range, route and upgrade order become your decision. Spamming one tower is not a strategy. THREE AGES Stone and archer towers of the First Age, cannons and mortars of the Powder Age, machine guns and tesla coils of the Modern Age. Each age brings its own enemies and its own answers; armored, flying, shielded and healing units all have a readable counter. REAL DIFFICULTY Difficulty was measured and balanced all the way to level 120. Your opening investment, your wall health and the order you unlock towers genuinely matter. When you lose, the game tells you why. ENDLESS AND RANKED Endless mode opens as the campaign progresses. In ranked mode your score is verified on the server: everyone plays the same fixed loadout under the same rules. PLAYABLE WITHOUT ADS Rewarded ads are optional and start only when you press the button yourself. There are no app-open ads and no banners. An interstitial plays when a level ends, and the ad-free purchase removes it. The whole campaign can be finished without watching a single one. TURKISH AND ENGLISH Every string was written in both languages; you can switch in-game. PLAYS OFFLINE The campaign works without a connection. An account is optional; if you create one, your progress is kept in the cloud and waits for you on your next device.
