Xalo

Drag away from a planet to fling a satellite into space, then watch Newton decide whether you built an orbit or an expensive hole in the ground.

Gravity is real here: F = GM/r², integrated every frame, so every path is something you caused. A satellite that looks stable at launch can spiral in twenty seconds later because you were forty pixels short on velocity. Working out why is most of what you’re doing.

How it plays

• Click and drag from the planet’s surface. Direction sets the heading, length sets the launch velocity.
• Release and the satellite is on its own — gravity pulls in, momentum carries forward, and the ellipse falls out of the difference.
• Six satellite types, each with its own mass and handling.
• Build enough stable orbits before the clock runs out.

Why it’s a speck

You learn the one mechanic in about ten seconds and then keep getting it slightly wrong. It opens straight into play.
