How It Works
You control a red square. Blue circles patrol in fixed patterns. Touch any blue circle and you die. Reach the green zone on the other side to clear the level. That's it. No power-ups, no shortcuts, no mercy.
Controls:
- Arrow keys or WASD to move
- On mobile: virtual d-pad overlay
Tips for Survival
- Watch patterns first. Don't move immediately. Study the blue circles for a full cycle before committing
- Move between gaps, not through them. Time your movement to slip between two circles, not race past one
- Diagonal movement helps. Pressing two arrow keys at once lets you move diagonally, which opens up paths that straight movement can't reach
- Patience beats speed. The game rewards waiting for the right moment, not rushing
