This game is a curiously well thought out fun game. You plant trees and guard them to grow while getting hit and a spider destroys them. After you have enough full grown trees the screen changes, you then use them in puzzles. The more trees you get at the beginning, the farther you can make it through the puzzles.
You plant them, they eat through the ground, smash a larva, and you retrieve the trees to reuse them again, until you have used up your trees from larva hatching, not crushing them in time. You plant and move the trees as if you have power over them.
The back of the manual I must have wrote in ink the games name, it also has some blemishes.
The cartridge contacts are well cleaned, cartridge also cleaned. I tested this for more than and hour and it works very good.
