Ruin Engine

🎮 What is "Ruin Engine"?

---

You are a lone ship, hurtling down an endless neon corridor.

Waves of zombies swarm from above — and the only way to survive is to keep moving, keep shooting, and make smart choices at every gate. 

Math operator gates fall across your path, splitting the road in two. 

Pass through the right side and your squad grows. 

Take the wrong side and your numbers shrink. 

It's fast, it's relentless, and every run is different.

✨ Key Features

---

・Math Gates: 

Every few seconds, a pair of gates drops across the screen. 

One side might add to your count (+1 to +4), another multiplies it (×2). 

Sometimes one side subtracts — choose wisely.

・Automatic Firepower: 

Your ship shoots continuously. 

The more allies you have, the wider the bullet spread — up to 8 simultaneous shots covering the full lane.

・Zombie Horde: 

Enemies home in on your position. 

Bigger zombies take more hits. 

The longer you survive, the faster and tougher they get.

・10,000 Point Challenge: 

Survive long enough to hit the score limit and achieve true Game Complete.

・Bilingual Support: 

Toggle between English and Japanese instantly.

・Keyboard & Touch: 

Arrow keys for PC, swipe for mobile — play anywhere.
