Lander

Lander does exactly what its name promises: rotate a small ship, fire its engine, and bring it down gently, pointy end up, on a landing pad scattered across procedurally-varied terrain. It's the 1969 arcade formula rebuilt clean in plain JavaScript with no dependencies, wrapped around a numbered "Daily Challenge" that gives the same terrain seed to everyone on a given day — a light, effective reason to open it again tomorrow.

The game grades its own controls, and the grades hold up

What makes this one worth singling out is unusual: the title screen itself includes a live checklist under "Test the controls," asking the player to tap the center of the screen, tap the left side, tap the right side, and then hold the center while tapping a side — each with its own checkbox that ticks only once that exact gesture is detected. That's an unusually testable claim for a web game to make, and it was taken up directly rather than trusted. Individual taps on all three zones ticked their boxes immediately on a simulated touchscreen. The fourth claim needed a genuine two-finger touch — not two taps in sequence, but two touch points held on the canvas at the same time — which was dispatched as a real simultaneous multi-touch event through Chromium's input pipeline rather than simulated with a script-level hack. It worked: the checkbox ticked, and the on-screen lander visibly rotated while thrusting, exactly the combined motion a real player holding thrust while tapping a rotation key would produce. The equivalent keyboard checklist on desktop (up arrow, left arrow, right arrow, holding up while pressing a side) was confirmed the same way with held key combinations.

Once every box was ticked, the game moved straight into "Daily Challenge 1278" without any further input needed, and the lander's drift, rotation and descent toward a jagged gray terrain silhouette all tracked the inputs given during testing — the control test isn't a disconnected demo, it's gating entry into the same physics and the same input handling the real game uses.

A clean, well-liked classic

Visually it's simple and effective: a gradient-shaded ship against a starfield, terrain rendered as flat gray silhouettes, and clear text HUD elements (challenge number, a small stat readout) that stay legible at both phone and desktop sizes. The source itself is unusually well cared for — a plain-JavaScript, no-dependency codebase with explicit touchcancel handling so a control can't get stuck "on" if a finger slides off the screen mid-hold, which is exactly the kind of edge case that trips up hastier touch implementations elsewhere on this shelf. A Show HN post for this exact project reached 564 points, and the repository carries 178 stars — both checked directly rather than assumed, and both indicate a genuinely well-regarded independent project rather than an obscure find.

Final verdict

Lander earns its place by making an unusually strong, unusually specific claim about its own touch controls and then backing every part of that claim up under direct testing, including the hardest part — real simultaneous multi-touch — that most games on this shelf don't attempt at all. It's a faithful rather than inventive take on a 55-year-old genre, and the missing licence file keeps it out of full trust, but a control implementation this carefully built and this thoroughly verifiable is rare enough to recommend on that alone. Add it.
