Read full description

過去の自分から、逃げ続けろ。 「PastMe」は、前のラウンドで自分が通った動きが“ゴースト”として再現される、シンプルな2Dアクションゲームです。 ルールは簡単。 画面をタップして移動し、フィールドに現れる欠片を集めるだけ。 しかし、ラウンドが終わると―― さっきまで操作していた「過去の自分」が、新たな敵として現れます。 過去の自分は、あなたが前のラウンドで動いた軌跡をそのまま再現します。 ラウンドを重ねるほどゴーストは増え、逃げられる場所は少しずつ狭くなっていきます。 「次のラウンドでは、この動きが敵になる。」 今を生き残るだけでなく、未来の自分が困らないルートを考えることも重要です。 シンプルな操作の中に、判断力と駆け引きが生まれるスコアアタックゲームです。 あなたは、何人の「過去の自分」から逃げ続けられますか?
