Doodle Hop
Vertical hopper across five biomes: forest, night city, clouds, space and the void. Each altitude brings new traps, monsters, shooting, a jetpack and a shield.
How to play
Move ← → (keys, tilt or tap the screen sides) — bouncing off platforms is automatic. Tap the upper screen or press ↑ to shoot a monster; you can also stomp it from above. The higher you climb, the newer the biome and the nastier the traps: platform-edge spikes, spinning saws, melting and slime platforms, conveyors, wind gusts, black holes and laser drones (the beam is telegraphed first). Springs and the jetpack launch you, the shield absorbs one trap. Combo: kill monsters without touching a platform.
