世界は止まらない。 キャラクターは自動で前へ進み、次々と現れる敵と戦い続ける―― 本作は「放置×成長×周回」を融合した横スクロール型オートバトルRPGです。 プレイヤーは操作せずともキャラクターが自動で進み、敵と接触することで戦闘が発生します。倒した敵から経験値を獲得し、ポイントを使ってステータスを自由に強化。HP・攻撃力・スピード・回復力・運の5つの能力を伸ばし、自分だけの成長ビルドを作り上げましょう。 距離が進むほど敵はどんどん強くなり、新たなフェーズへ突入。通常敵だけでなく強敵やボスも出現し、緊張感のあるバトルが続きます。 しかし敗北しても終わりではありません。HPが0になるとスタート地点へ戻りますが、強化した能力はそのまま。繰り返すほど確実に強くなっていきます。 さらに本作には「プレステージ（周回）」システムを搭載。 ゴールに到達すると世界をリセットし、より強力な敵と報酬倍率が解放されます。周回を重ねるほど成長スピードが加速し、爽快感と中毒性が一気に高まります。 敵を倒すとアイテムがドロップすることもあり、ステータスを直接強化するさまざまな効果を獲得可能。 シンプルながら奥深い成長システムで、放置している間も着実にパワーアップできます。 【ゲームの特徴】 ・放置で進む横スクロールオートバトル ・距離によって変化する敵フェーズシステム ・自由に育成できる5種のステータス強化 ・敗北しても成長が残るローグライク的進行 ・周回で倍率が上がるプレステージ要素 ・アイテムドロップによるビルド強化 操作はシンプル、成長は無限大。 短時間でも長時間でも楽しめる放置型成長RPGをぜひ体験してください！
