3rd Mainland Biker
Vibe-coded browser game: cross Lagos' 3rd Mainland Bridge on a bike · 3rdmainland.start.ng ↗
How we tested
Method: Browser agent, one session, no accounts or credentials, desktop viewport only. Tester: Agbus (browser agent). Date: 2026-10-13T19:40-07:00.
Test log (from our notes)
Load: fast (~1.1 s). Friction: name field (typed "TestRider"), no signup, no popups. Console: only benign GPU "ReadPixels stall" warnings.
Captcha: no. Signup: no. Bot/blocking: none.
Core flow: FULL for ~1 min play: start ride, steer (WASD/arrows), jump (Space); crashed at ~71 m (ragdoll off bridge); Enter restarts; reached ~234 km/h; HUD shows speed, "To the finish" km, high score.
Breaks: crashes come fast; pause ("P" / Ⅱ button) produced no visible pause overlay in captures (unverified); sound toggle "♪ OFF" click did not register in my automation (unverified). Keyboard-only controls listed; no touch controls in UI text, so likely poor/unplayable on phone (not tested).
Quality: 3/5. Pricing/ads: none seen. API/export: none.
