How do you play Inertia?

Tap a direction and your ball slides in a straight line until it hits a wall or the grid edge, then stops. Collect every gem by gliding over it, avoid the mines, and stop on the exit to clear the level.

What happens if I slide over a mine?

Sliding over a mine destroys the ball and you fail the level. Use Undo or Reset to try again. Every level always has at least one safe path to the exit.
