Flappy Submarine Adventure

Deep water stretches into an endless tunnel. In Flappy Submarine Adventure, a small submarine drifts through that underwater passage with mines hanging in the route and solid walls closing off both sides. The run fits both kids and adults, with a steady arcade setup that tracks survival by distance and pressure inside the tunnel.

How to play?

Press and hold to raise the submarine higher in the water, then release to let it drop back down. Mines remove a life on contact, and scraping a wall does the same. Seconds spent moving ahead add points to the score, pushing the record higher as the tunnel continues and the path gets tighter.
