About

Spaceship;Capture Space Debris

Features
Read full description

This app is a game that virtually shoots cast nets from a spaceship to capture space debris, UFOs, etc. and score points. We aim to increase the highest score even though the number of remaining cast nets is limited. Space debris does not escape, so there is no need to hurry, it is a game that you can enjoy while thinking calmly. Functions; The spaceship moves up, down, left, right, and back and forth by operating the buttons of the head-up display(HUD) that are superimposed on the foreground scenery that changes as it moves. It's a bit like maneuvering a drone. You can cast a net by touching the panel button at the bottom center of the screen. Touch the center of the panel button to cast it to the center of the screen. If you touch the upper left, it will cast to the upper left of the screen, if you touch the upper right, it will cast to the upper right of the screen, if you touch the lower left, it will cast to the lower left of the screen, and if you touch the lower right, it will cast to the lower right of the screen. Touch the intermediate position to cast in the intermediate direction. The stage ends when the remaining number of cast nets reaches zero. The score is 3, 5, 7 depending on the type of space debris. If you capture a UFO, you will get 20 points, and if you get a gold star , you will get 10 points. Every time you get a few gold stars , a series of UFOs will appear one after another. UFOs are easier to capture if you move the spaceship in the direction the UFO travels. By devising a strategy in this way, you can aim to increase the highest score. It may be a game where you can test your smartness.
