The Helicopter Game is one of the oldest one-button games on the web: a helicopter flies right through a scrolling cave, and holding the mouse makes it climb while releasing lets it fall. Touch the walls or a block and the run ends.
It dates from the early 2000s and it is still a genuinely good design — the physics have momentum, so you're steering against inertia rather than moving a cursor, and the cave narrows as you go.
Rapid short taps rather than holding. There's no neutral input — you're always rising or falling — so level flight is a rhythm of small corrections.
It's an early-2000s Flash classic, one of the first one-button browser games to become widely popular. This version runs without Flash.
Yes — one of the lightest games on the site, with nothing to install.
