Watch the tutorial collision
The source tutorial begins with a zombie moving toward a brain behind a laser fence. Its next hint notes that the zombie was destroyed and the fence disappeared. That demonstration is the key opening rule: a visible barrier is not a promise of permanent protection, and another approaching zombie may need a new defensive action.
Wait until drawing is enabled
The tutorial progresses through hints and a demonstration before enabling player drawing and enemy spawning. If the first screen does not respond as expected, read the current hint rather than treating it as a broken control. The game deliberately introduces the interaction before allowing the defensive loop to begin.
Read paths before drawing repeatedly
As an opening exercise, follow one approaching zombie and decide where a fence would intersect its route. Observe the resulting collision before adding many unrelated lines. This is practical learning advice drawn from the tutorial’s mechanic, not a claim about an optimal survival strategy, a completed level or a verified phone gesture.
