Double Orbit takes a familiar idea and tunes it until it clicks. Here you get 6 lives, bosses with 50 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.
Nothing here needs a tutorial or a wiki. Controls are one gesture, the goal is one sentence, and the difficulty comes from execution rather than homework. That is exactly what a browser game should be.
