Straight to the point: Bubble Tower is spawn waves every 0.64 s at level one and a 17% bomb cap, playable in your browser right now. It is tuned for quick runs, honest difficulty, and controls that make sense the first time you touch them.
Bubbles rise from the bottom at their own pace; pop them before they escape at the top. Same-colour chains build a combo multiplier, bombs punish a careless tap, and three escapes cost a life. The spawn waves every 0.64 s at level one and a 17% bomb cap.
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.
