Zip Trail

Hold to draw a single continuous zipline path across the level; release to launch every kobot at once — the more bots that hit the treasure, the bigger the payout.

Core mechanic

Draw-once puzzle: one finger stroke defines the path, bots ride it, collisions bounce them off; survive the bounce to bank loot.

Controls

Hold and drag to draw the zipline; release to launch.

Theme

Canyon mining outpost — rope bridges over pit spikes, kobolds dangling from belts.

Why now

Pulls Kobots' zipline tool into a one-finger draw mechanic that fits one-thumb mobile.

Hook
6/10

Draw-to-physics launch is a clear visual beat, but a published 'Zip Line Puzzle Game' on Google Play already uses near-identical 'drag the rope, launch one-finger' framing.Direct competitor: 'Zip Line Puzzle Game' – drag rope to create path, avoid obstacles, same one-finger draw + release loop.

Virality
6/10

Bouncy launch moments are inherently streamable and short-form friendly, as proven by Draw Climber-style hits; collision banking creates a punchline per run.'Draw Climber' cited as benchmark similar draw-one-line viral hit.Draw-one-line hypercasual content performs on short-form video.

Simplicity
8/10

Trivial 2D physics + line renderer + one input; Kobots core is just a Lemmings-style wrapper around three tools (rope/zipline/fan) – buildable in days.Kobots shipped in 13 days with Phaser 3; mechanics are simple physics primitives.

Monetization
6/10

Standard hypercasual ad loop (interstitial per launch, rewarded revive) fits the draw→release→result cadence; Voodoo still does $778M/yr but is shifting off pure hypercasual, so per-title CPMs are softer.Voodoo 2025: $778M revenue, 169M MAU, hypercasual decaying ~40%/yr – ads work but ARPDAU squeezed.

Whitespace
3/10

Crowded: Zip Line Puzzle Game already on Play Store with same mechanic, plus Draw Climber, Happy Glass, 'Draw the Line' lineage, and general one-stroke puzzle saturation on app stores.Existing zipline-draw competitor on Google Play.'Line Drawing: No Lift Puzzle' – another one-finger draw puzzle in same category.
