「月面郵便」は、月の重力で曲がる軌道を読み、一通の手紙を赤い郵便受けへ届ける一投型の物理ゲームです。 荷物を引いて向きと強さを決め、指を離して投函します。まっすぐ狙っても、月や惑星の引力で航路は大きく曲がります。失敗した軌道を見て、次の一投を少しだけ直す。その積み重ねで、難しい航路が自分の手でつながります。 ・月、惑星、太陽、ブラックホール、反重力星、白孔などが登場する全500便 ・スイングバイ、画面外からの帰還、複数天体を使う高難度航路 ・200便クリア後に解放される「極限ランダム航路」 ・最後の一投を結果画面まで動画にして共有できるリプレイ機能 ・章クリア、全500便完走、珍しい失敗や危険航路を含む60実績 ・Game Center実績連携 ・BGM、重力・天体音、効果音の個別音量設定 同じ便で3回届かなかったあと、軌道を最大2分先まで確認できる「軌道切手」が解放されます。最初の5回分と、1日1回のログインボーナスは無料です。必要な場合だけ、10枚セットをアプリ内で追加できます。 広告、行動追跡、利用状況解析はありません。進行データは端末内に保存されます。
