GEODE PASS

Burrowers march on the Geode Core. Build crystal towers, feed them gold, hold the line for ten waves.

Move the build marker with WASD / arrows — tap the ◀▲▼▶ pads on touch.
Pick a tower with 1 / 2 / 3, place it with Space or a click on a glowing pad.
Click a tower to inspect it, U upgrades, X sells it back.
Enemies that reach the Core cost lives. Lose all 20 lives and the run ends.

Victory

Spark (40g): fast single-target bolts. Cheap and cheerful.
Lance (75g): long range, heavy damage, slow firing — good on the far corners.
Hail (95g): shatters every burrower in a ring around it — loves tight packs.
Upgrades (U) raise damage, range and fire rate; level 3 is max. Sell (X) refunds 60%.
Send waves early with N / "Send next wave" for a gold bonus. Waves get heavier; wave 10 brings a matriarch.
Mouse: click a pad to move the marker, click again (or Space) to build, wheel to zoom.
P pauses, F fast-forwards, M mutes, ? opens this panel.
