Seeds are primarily used to plant plants. The player starts with one seed the first time they play the game, and more seeds can be collected from matured plants. Additional starting seeds can be purchased as an upgrade.

10 seeds are used to build Moai Smash. Seeds can also be given to the General to unlock the Laser Rifle for 100 seeds, and purchase weapon power-ups for 25 seeds.

When planting seeds, due to the way available space is checked, it is more space efficient to plant seeds moving from left to right than from right to left.

Directional Spacing

The Pew Pew Tower was built first, then five seeds were planted on either side, moving away from the tower and planting as close as possible to the previous plant.
