Thorn Moth
A bramble moth. When it turns pink it charges; now and then it drops a seed.
Bramble Birds — Map 6/6
The Heart of the Brambles
The thicket has a heart, and it is still beating.
The Heart of the Brambles
The Heart of the Brambles is the sixth and final map. Walls of thorns grow across the arena after a warning, vine lashes strike inside a red strip, and roots sprout from the floor.
Thorn moths charge once they turn pink and sometimes drop a seed, thorny seeds beat faster and faster until they burst into a fan of spines, and thorny beetles puff up and fire three spines in a fan. Columns of hot air rise from the third wave on.
Hazard: Walls of thorns grow after a warning, vine lashes strike inside a red strip, and roots sprout from the floor.

What winning unlocks
Winning unlocks Endless mode for this map and the next difficulty tier here. Win all six maps on Hard and Hell opens everywhere.
Difficulty
Every map, including The Heart of the Brambles, has the same 4 difficulty tiers.
| Difficulty | Rules |
|---|---|
| Easy | No extra rules. |
| Medium | Shop 25% pricier and bugs 10% faster. |
| Hard | Plus more enemies at once, with 10% more health. |
| Hell | Plus one more spike per wall, nest twice as pricey and a boss with +50% health that attacks more. |
Hell is the final difficulty tier, unlocked once all six maps have been beaten on Hard. It stacks on every earlier rule: one more spike per wall, a nest that costs twice as much, and a boss with 50% more health that attacks more often.
Endless mode
Endless mode for a map opens when you win that map in Story mode, on any difficulty (the first map is open from the start). Once you down the boss, the waves never stop: every fifth one brings back the boss, tougher each time.
