Aim, then let go
Drag on the board or move the mouse to swing the launcher. The dotted line shows where the seed will fly until its first bounce, then hints at the rebound. Let go, click or press Space to shoot. On a keyboard, Left and Right aim, holding Shift makes the aim finer, and P pauses. Each shot uses one seed from the tray at the top left.
Light every orange peg
Any peg or wooden brick the seed touches lights up, and lit pieces drop away when the seed leaves the board. Light all the orange pegs, marked with a diamond, to clear the garden; the counter at the top right shows how many are left. Green pegs, marked with a leaf, burst and light everything close to them. Land a falling seed in the moving basket and you get it back. If the seeds run out before the oranges do, retry the garden.
