      <description>&lt;p&gt;Exciting news for puzzle game enthusiasts! The new puzzle game 'LOOP' has just been released and it's already creating a buzz among Tetris addicts. With a play count of 56 this week, it's clear that this game is on its way to becoming the next big thing.&lt;/p&gt;

&lt;p&gt;'LOOP' offers a fresh take on the classic tile-matching genre, incorporating elements that will appeal to those who have spent countless hours playing Tetris. The game challenges players to strategically place falling blocks on the grid, aiming to match three or more of the same color to clear them. As you progress, the game becomes increasingly difficult, with higher levels introducing more complex block patterns.&lt;/p&gt;

&lt;p&gt;What sets 'LOOP' apart is its unique 'tile-flipping' mechanic. When you clear a group of blocks, surrounding blocks can also be affected, leading to chain reactions and higher scores. This adds a layer of strategy and excitement that keeps players coming back for more.&lt;/p&gt;

&lt;p&gt;The game features several modes to keep things interesting. In Time Attack mode, players race against the clock to achieve the highest score possible. Endless mode challenges players to keep clearing blocks until they can no longer do so. Multiplayer mode allows you to compete against friends to see who can achieve the highest score.&lt;/p&gt;

&lt;p&gt;According to the developers, 'LOOP' is designed to stimulate the brain's reward system, meaning that the more you play, the more dopamine you'll release, leading to a highly addictive experience. It's the perfect game for anyone looking to satisfy their puzzle-solving cravings.&lt;/p&gt;

&lt;p&gt;If you're a Tetris addict or simply love puzzle games, 'LOOP' is a must-try. Download it now and experience the thrill for yourself!&lt;/p&gt;

      <description>&lt;p&gt;Hello everyone,&lt;/p&gt;

&lt;p&gt;We are excited to announce the release of our new puzzle game, 'LOOP'. With a play count of 63 this week, it's slowly gaining attention. The theme of the game is 'The Aesthetics of Chain Reactions'. We aimed to create a gameplay experience that is both simple and profound.&lt;/p&gt;

&lt;p&gt;In 'LOOP', players combine various shaped pieces displayed on the screen to create chain reactions. Simply placing pieces can result in beautiful chain reactions, providing an almost artistic experience.&lt;/p&gt;

&lt;p&gt;During the development of this game, our team challenged the 'never-finishing disease', a common phenomenon in game development where the finish line seems endless and improvements continue indefinitely. We fought against this disease and did our best to deliver the best gaming experience.&lt;/p&gt;

&lt;p&gt;'LOOP' is not just a puzzle game. It stimulates players' creativity and logical thinking, embodying the aesthetics of chain reactions. Once you play, you will be drawn into its charm.&lt;/p&gt;

&lt;p&gt;This week's play count of 63 is just the tip of the iceberg. We hope that this game will be loved by many players and that the play count will skyrocket. As the play count increases, competition within the community will intensify. Challengers aiming for the top spot, it might be you who threatens that position!&lt;/p&gt;

&lt;p&gt;Challengers, play with no regrets! Experience the aesthetics of chain reactions in 'LOOP' and aim for the top!&lt;/p&gt;

      <title>脳汁の秘密：なぜ私たちは報酬を求めるのか</title>
      <dc:creator>松下治正</dc:creator>
      <pubDate>Sun, 26 Apr 2026 06:48:44 +0000</pubDate>

      <guid>https://forem.com/harumasa_matsushita/noy-zhi-nomi-mi-nazesi-tatihabao-chou-woqiu-merunoka-262o</guid>
      <description>&lt;p&gt;「脳汁」という言葉は、一般的にドーパミンの放出によってもたらされる快感を指します。ドーパミンは、報酬系に関与する重要な神経伝達物質であり、私たちが楽しい、やりがいのある、または報酬的な活動に従事したときに放出されます。この化学物質は、私たちの行動を動機づけ、特定の行動を繰り返すように促します。&lt;/p&gt;

&lt;p&gt;脳汁が放出されると、私たちは幸福感や満足感を経験します。これは、食べ物、社会的相互作用、運動、さらにはゲームやアプリの使用などの活動で起こります。これらの活動は、私たちの脳に報酬を与え、ドーパミンの放出を引き起こします。&lt;/p&gt;

&lt;p&gt;ただし、脳汁の過剰な放出は依存症や強迫的な行動につながる可能性があるため、注意が必要です。適度な報酬的な活動は心身の健康に良い影響を与える可能性がありますが、過剰な使用は逆効果になる可能性があります。&lt;/p&gt;

&lt;p&gt;結論として、脳汁は私たちの行動を形作る重要な要素です。適切に管理されれば、私たちの生活にポジティブな影響を与えることができます。&lt;/p&gt;

      <description>&lt;p&gt;新作パズルゲーム「LOOP」が話題になっています。このゲームは、@Harumasa-Matsushitaが開発した「完成させない病」に挑戦したプロジェクトの一部です。開発者は徹底した合理主義者の視点から、プロジェクトの完了基準とプロセスの見直しを行い、より効率的な開発サイクルを目指しています。&lt;/p&gt;

&lt;p&gt;ゲームのテーマは「論理の迷宮を解き明かせ」で、プレイヤーは複雑なパズルを解きながら進んでいきます。IQ140以上推奨とされており、その難易度は非常に高くなっています。現在、プレイ数は63件とまだ少ないですが、そのユニークなアプローチと高い難易度が、パズル愛好家たちの間で話題となっています。&lt;/p&gt;

&lt;p&gt;技術的な背景として、Qiitaでは「開発完了しない病への挑戦」という記事が投稿されています。この記事では、puzzlegamedevのプロセス改善やindiegameでの合理主義開発について詳しく解説されています。開発者によると、合理的なアプローチでプロジェクトを進めることにより、より効率的な開発が可能になるとのことです。&lt;/p&gt;

&lt;p&gt;「LOOP」のプレイは&lt;a href="https://plicy.net/GamePlay/227378%E3%81%8B%E3%82%89%E5%8F%AF%E8%83%BD%E3%81%A7%E3%81%99%E3%80%82%E3%81%95%E3%82%89%E3%81%AB%E3%80%81%E3%82%B2%E3%83%BC%E3%83%A0%E3%81%AE%E8%A9%B3%E7%B4%B0%E3%82%84%E3%83%97%E3%83%AC%E3%82%A4%E5%8B%95%E7%94%BB%E3%81%AFhttps://t.co/4edd9dLiFq%E3%81%A8https://is.gd/YfIHW7%E3%81%A7%E3%83%81%E3%82%A7%E3%83%83%E3%82%AF%E3%81%A7%E3%81%8D%E3%81%BE%E3%81%99%E3%80%82%E3%81%93%E3%81%AE%E3%82%B2%E3%83%BC%E3%83%A0%E3%81%AE%E6%8C%91%E6%88%A6%E7%9A%84%E3%81%AA%E3%82%B3%E3%83%B3%E3%82%BB%E3%83%97%E3%83%88%E3%81%A8%E8%A4%87%E9%9B%91%E3%81%AA%E3%83%91%E3%82%BA%E3%83%AB%E3%81%AF%E3%80%81%E3%83%97%E3%83%AC%E3%82%A4%E3%83%A4%E3%83%BC%E3%81%AB%E6%96%B0%E3%81%9F%E3%81%AA%E4%BD%93%E9%A8%93%E3%82%92%E6%8F%90%E4%BE%9B%E3%81%97%E3%81%A6%E3%81%84%E3%81%BE%E3%81%99%E3%80%82%E3%81%9C%E3%81%B2%E6%8C%91%E6%88%A6%E3%81%97%E3%81%A6%E3%81%BF%E3%81%A6%E3%81%8F%E3%81%A0%E3%81%95%E3%81%84%EF%BC%81" rel="noopener noreferrer"&gt;https://plicy.net/GamePlay/227378から可能です。さらに、ゲームの詳細やプレイ動画はhttps://t.co/4edd9dLiFqとhttps://is.gd/YfIHW7でチェックできます。このゲームの挑戦的なコンセプトと複雑なパズルは、プレイヤーに新たな体験を提供しています。ぜひ挑戦してみてください！&lt;/a&gt;&lt;/p&gt;

      <title>【バズり中】今週プレイ63件！オカルト 畳返しパズル「Legend of Occult Puzzle」開発者による裏話！</title>

      <guid>https://forem.com/harumasa_matsushita/bazurizhong-jin-zhou-purei63jian-okarutoxdie-fan-sipazurulegend-of-occult-puzzle-kai-fa-zhe-niyoruli-hua--2h2l</guid>
      <description>&lt;p&gt;Hello, I'm Harumasa Matsushita, an indie game developer. Recently, I released a new puzzle game "Legend of Occult Puzzle (LOOP)" that can be played instantly in a browser. This game is a fast-paced combo x occult battle puzzle where you flip tiles on the board to create chains. In this article, I'd like to share some technical insights on how I implemented the "visual impact" that is the core of this game.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Creating an isometric space without "perspective"
The charm of quarter view is that it can balance the alignment and visibility of a 2D puzzle while being 3D. To achieve this in Three.js, I used an OrthographicCamera (orthogonal projection camera) instead of the usual PerspectiveCamera.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Key points of implementation&lt;br&gt;
By removing the perspective (perspective), the tiles in the front and back are drawn in the same size, creating an accurate sense of operation as a puzzle.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;Intuitive "tile selection" with Raycaster&lt;br&gt;
To manipulate objects in 3D space with a mouse or tap, we need to convert the 2D coordinates on the screen to 3D space coordinates. This is where THREE.Raycaster comes into play.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Mathematical approach to realize "tatami flipping (flip)"&lt;br&gt;
The biggest visual impact of this game is the "effect of tiles flipping in a lump". This is achieved by temporarily grouping multiple selected tiles into one group (THREE.Group).&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Steps&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Extract the tiles within the swipe range.&lt;/li&gt;
&lt;li&gt;Calculate the central coordinates of the range.&lt;/li&gt;
&lt;li&gt;Place a new THREE.Group in the center and move the tiles to its child elements.&lt;/li&gt;
&lt;li&gt;Rotate the THREE.Group itself 180 degrees around the X or Z axis.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Play: &lt;a href="https://plicy.net/GamePlay/227378" rel="noopener noreferrer"&gt;https://plicy.net/GamePlay/227378&lt;/a&gt;&lt;/p&gt;
