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 follows the inverse-square law here: acceleration falls as 1/r², stepped forward every frame. The strength is tuned for play, but the path still starts with your launch. 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 gravity pulls in while momentum carries forward. Hold Space to boost a selected satellite; C toggles circularization assistance.
• Six satellite types, with different sizes, scoring bonuses, and special jobs.
• 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.
