Petals of Doom

Trapped within an eerie space cavern, the only way home is to help the flower plantation reach fully growth. Only then will energy curtains blocking your way finally disappear. But, true to all classic space shoot-outs, the plant-hating bugs are out to stamp your flowers to the ground. See the free world again - only if your trigger finger can match the challenge.
