Wonder Planet (Japan) — About this game
Wonder Planet (Japan) sends a starship between aerial enemies and defended ground targets. Twin bullets attack the air, while dropped bombs strike the position marked ahead of the ship. Destroyed targets supply credit for shops, where the player can improve the engine, obtain weapons or buy protection. Collecting letters to complete a word earns an additional reward. The end of each planet brings a larger enemy that must be defeated before the journey can continue, making both careful aiming and useful purchases part of the route.
