Runaway Courier — a 3D

Runaway Courier — a 3D rooftop runner inside Snapchat

Endless runners are fun for a minute, then they all feel the same. Runaway Courier gives every run a purpose: deliver the parcel before a cop and his bulldog catch you.

What I built • A 3D rooftop runner across 7 worlds and 21 levels: old town, glass towers, desert kasbahs, forest bridges, snowy peaks, harbour docks and floating sky islands • Swipe controls built for thumbs: change lanes, jump, slide, with every gesture buffered so nothing feels missed • A live chase: each mistake brings the cop and his bulldog closer; run out of energy and you are busted • An economy that keeps players coming back: deliveries, tips and clean-run bonuses fill season earnings and unlock new levels • English and French, progress saved with Snap storage, the whole game in a 2.7 MB package

Result • Published on Snapchat as a public game Lens (October 2026), approved by Snap in under an hour • Submitted to the Snap × Lenslist Web Lens Game Challenge • Game rules, collisions and missions covered by automated tests
