Resource and Upgrade Pacing

General resource logic: prioritize economic rolling, then establish the minimum defensive line for the current wave, and finally consider utility efficiency.

Suggested pacing:

1. Push economy to critical returns (e.g., early level 1–2; fine-tune per mode values);
2. Build the minimum main-line defense strength (one core spot + auxiliary damage covering the entrance);
3. Add control (slow/area/sensing) at the right time to improve kill efficiency;
4. Focus upgrades on core damage to form a positive feedback loop of "economy → core tower".

Common mistakes and fixes:

• Mistake: upgrading all towers evenly. Fix: concentrate resources on the core;
• Mistake: over-defending before economy stabilizes. Fix: keep the growth curve of income;
• Mistake: ignoring utility/supply bottlenecks. Fix: check the supply chain and buff coverage before high pressure.
