Locust
Hops along in short bursts — once it flashes red, it charges.
Bramble Birds — Map 4/5
The Viper's Dunes
The sand breathes — and it pushes back.
The Viper's Dunes
The Viper's Dunes add thermals: columns of hot air that punch straight up through the arena and shove you off your rhythm if you're caught in one.
Locusts hop in fast, dung beetles lob a ball of mud that bounces three times, spiny rollers curl up and bounce clear across the dunes, and vultures glide overhead, dropping bones straight down.
Hazard: Thermals punch up through the sand and shove you off your rhythm.
Bestiary
The 4 enemies you meet across this map's waves, in the order they first show up.
Dung Beetle
Lobs a ball of mud that bounces three times before it breaks apart.
Spiny Roller
Curls into a spiky ball and bounces across the dunes, each bounce landing higher than the last.
Vulture
Glides up high — when it screeches, it drops a bone straight down.
Boss
???
This boss stays in shadow until you beat The Viper's Dunes for yourself — no spoilers here.

Difficulty
Every map, including The Viper's Dunes, has the same 4 difficulty tiers.
| Difficulty | Rules |
|---|---|
| Easy | No extra rules. |
| Medium | Enemies get +25% health, the shop costs 25% more, and each wall gets one more spike. |
| Hard | On top of that: more enemies at once, one less heart to start, and bugs move 20% faster. |
| Hell | On top of that: the nest heals half as much, and the boss has +50% health and attacks more often. |
Hell is the final difficulty tier, unlocked once all five maps have been beaten on Hard. It stacks on every earlier rule: the nest heals half as much, and the boss has 50% more health and attacks more often.
Endless mode
Endless mode unlocks by beating a map in Story mode (the first map is open from the start). Once you down the boss, the waves never stop — every fifth one brings back a tougher boss.
