《是男人就下100層》（NS-Shaft 是男人就下100層）是一款重現經典像素下墜闖關玩法的免費網頁小遊戲，無需下載、打開瀏覽器即可立即遊玩。遊戲規則看似簡單：畫面頂端的尖刺天花板會不斷向下逼近，玩家必須持續控制角色向下跳躍、左右移動，找到安全的平台落腳，才能避免被尖刺天花板擠扁。
遊戲中設有多種平台機關，大幅提升可玩性與挑戰性：
- 普通平台：穩定可踩，是最安全的選擇。
- 尖刺平台：紅色帶刺地板，一踩即死，必須提前判斷並繞開。
- 崩塌平台：踩上去後木板會迅速碎裂崩塌，必須快速離開。
- 傳送帶平台：會持續向左或向右滑動，考驗玩家的方向控制能力。
- 彈跳墊：踩上去會被高高彈起，雖然可以加速衝關，但也可能讓角色彈得太高反被天花板尖刺擠扁，需要謹慎使用。
隨著下墜層數增加，天花板逼近的速度會逐漸加快，平台機關的出現頻率也會提高，遊戲難度層層遞進，目標是挑戰突破第100層，創造個人最佳紀錄並挑戰好友。遊戲內建血量系統，重摔落地會扣除血量，角色力竭死亡後可觀看一段廣告影片復活，恢復一半血量繼續挑戰，無需從頭開始。
本遊戲使用 HTML5 Canvas 技術打造，畫面色彩鮮明、操作流暢，支援電腦鍵盤方向鍵與手機觸控按鈕雙重操作方式，自適應各種螢幕尺寸，無論手機、平板或電腦皆可流暢遊玩，是辦公室、課間或通勤途中放鬆解壓的最佳休閒選擇。
NS-Shaft: 100 Floors Challenge is a free browser-based reimagining of the beloved classic falling-platform game, playable instantly with no download required. The premise is deceptively simple: a spiked ceiling is always closing in from the top of the screen, and you must keep moving downward and side to side to find safe footing before you get crushed.
The shaft is filled with varied platform hazards that keep every run fresh and challenging:
- Normal platforms — solid and safe to stand on.
- Spike platforms — bright red and instantly lethal, requiring quick reflexes to avoid.
- Collapsing platforms — crumble away moments after you land, forcing you to keep moving.
- Conveyor belts — slide you left or right, demanding precise directional control.
- Spring pads — launch you upward for a speed boost, but risk bouncing you straight into the deadly ceiling above.
As you descend further, the ceiling accelerates and hazardous platforms appear more frequently, creating a satisfying difficulty curve all the way to the ultimate goal: floor 100. A built-in life system tracks fall damage from hard landings, and when your character finally falls, you can watch a short rewarded ad to revive with half health and keep climbing down without restarting from scratch.
Built with HTML5 Canvas for crisp, colorful visuals and smooth performance, the game supports both keyboard arrow keys and on-screen touch controls, automatically adapting to any screen size — desktop, tablet, or mobile. Perfect for a quick stress-relieving break at the office, between classes, or during your commute.
