3Dパズルゲーム「GemPhysics3D」
【更新履歴】
・2026/1/7 バージョン1.0公開
・2026/1/7 バージョン1.1公開
・2026/1/8 バージョン1.2公開
・2026/1/12 バージョン1.3公開
・宝石を消していくゲームですが、
物理演算を使っています。
・ツムツムだとかと違うのは、
テトリスやぷよぷよみたいに
何もしなくてもどんどん落ちてくるので、
ややアクション性が高いというところです。
・PCで遊ぶブラウザゲームですが、スマホ版もあります。
・ダウンロードされる方はこちら。↓
【操作説明】
・宝石は、3つ以上並んでいる宝石のうち一つを
左クリックすると消えます。
・並んでいない宝石を左クリックしてしまうとミス。
（宝石が10個落ちてくる。）
・宝石をマウスの右ボタンでドラッグすると、
周囲の宝石が円を描くように移動します。
・宝石が箱の外にあふれ出るとゲームオーバー。
・制限時間内に、なるべく多くの宝石を消して
獲得したスコアを競います。
・箱の外をマウスの左ボタンでドラッグすると、
視点を回転させることができます。
【難易度を調整して特訓する方法】
・テンキーの+キーを押すと、玉が落ちてくる速さが上がります。
・－キーを押すと、速度が半分になります。
・パソコン版の実装はこちら。↓
