The verdict
The seven metrics (0–100)
Full breakdown in the Evaluation card below.
0s: Game starts. Top-down city grid. Your rescue craft is on a high rooftop.
2s: Two clusters of citizens appear on other rooftops. A safe delivery zone glows.
5s: Your finger draws a clean, glowing path connecting your craft, both citizen clusters, and the delivery zone.
10s: The craft zips along the path, collecting everyone.
15s: Delivery successful! A score pops up.
17s: A blue water line visibly sweeps up, submerging the lowest rooftops you just used. They turn dark grey.
The player journey
Clever strategist.
I see the whole board.
I've trapped myself.
I know the perfect opening move now.
A perfect clear on the hardest map.
Innovation
The rising floodwaters are the timer, the obstacle, and the direct consequence of player success, turning every victory into a permanent, destructive change to the game board.
What kills it
The player loses when they've created an 'unwinnable' board state — where the remaining citizens are on rooftops that can no longer be connected by a single, valid path to a safe zone.
Rules
Why it works
The core premise is high-stakes, visual, and instantly understandable in an ad.
The core loop creates its own difficulty curve without needing complex systems.
Simple one-thumb controls and short sessions are perfect for the mobile audience.
Intelligence report
A highly compelling puzzle concept where player success directly creates future obstacles, featuring exceptional ad testability but a potential risk of long-term repetitiveness.

Marketing hook
Ad promiseDraw the perfect rescue path before the rising floodwaters claim the city.
Playable angleThe city is sinking! Can you draw the path to rescue these citizens before the water cuts them off?
Buildability
Scope2 weeks
Cheapest buildA small grid of placeholder shapes where one play action updates the board and the run ends on a lose condition.
Originality scout
AngleLean hard into the spine — Players must draw optimal paths to rescue stranded citizens and deliver them to safety before the constantly rising floodwaters make crucial routes impassable. — as the one thing no neighbor game does.
