Iron Ship takes a familiar idea and tunes it until it clicks. Here you get 5 lives, bosses with 55 base HP every third wave, wrapped in a clean, distraction-free board that works just as well on a phone as on a laptop.
The power-up economy matters more than raw dodging. Homing missiles clear crowds, the shield buys one honest mistake, and hoarding either is how runs reach wave ten and beyond.
It suits anyone with a queue to wait in or a kettle to watch: students between classes, commuters, parents stealing ten quiet minutes. There is no meta-progression to lose and nothing to catch up on - a week away costs you nothing but a little sharpness.
Endless waves, 5 lives, a boss every third wave.
Iron Ship is filed under Kepung Shelf, and the decision comes down to one tag set: shooter, waves, boss. Those three words are the whole reason it is not sitting somewhere else.
The board is easy to read and the difficulty is Easy, so the interesting decision is not whether you can play it but when. Its rating across our own notes is 4.7 out of five.
Keep it if you play in short bursts. It rewards a second attempt far more than a first, and the second attempt costs nothing but the tap.
