The Jungle River — Bramble Birds

The Jungle River trades solid ground for open water: touch the surface and it doesn't spike you, it dunks you, leaving you soaked and flying slower for a few seconds.

Tiger mosquitoes buzz in fast and nervous, piranhas leap up from below, poison frogs launch their tongues from the walls, and snakes hang from the ceiling, swinging further out each time.

Hazard: The floor is water — it dunks you instead of spiking you, leaving you soaked and slow for a few seconds.

Bestiary

The 4 enemies you meet across this map's waves, in the order they first show up.

Tiger Mosquito

Small, fast and jittery — once it flashes red, it bites twice in a row.

Piranha

Lurks underwater, bubbles up to show how high it's about to jump, then leaps.

Poison Frog

Hops wall to wall, puffs up its throat to aim, then whips its tongue at you.

Snake

Hangs from the ceiling and swings a little further out each time — read how far it reaches before flying past.

Boss

???

This boss stays in shadow until you beat The Jungle River for yourself — no spoilers here.

Difficulty

Every map, including The Jungle River, has the same 4 difficulty tiers.

The Jungle River — 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.
