Why it's fun
- Three crystal towers. Sparks chew single targets, Lances snipe from afar, Hail shatters every burrower in a ring.
- Ten escalating waves. Crawlers, runners, brutes — and a matriarch boss on waves 5 and 10.
- Upgrade or sell. Three upgrade levels per tower; sell refunds 60% of everything invested.
- Call waves early for bonus gold and pressure — timing is your sharpest tool.
- 20 lives, one core. Every burrower that slips through bites your lives. Zero lives ends the run.
