A downloadable game for Windows

Under Line – Deep Sea Solutions is a single-player puzzle game that takes you to the bottom of the ocean with your oxygen line as your only connection to the surface.

As an employee of the Under Line Ltd maintenance division your task is to explore a flooded deep sea research facility to extract a valuable power core left behind.

The Manila Trench facility is in a terrible state and there are many challenges to overcome before you can reach the core. Thankfully, your colleagues at Under Line Ltd have equipped your diving suit with a state-of-the-art oxygen line retraction device. This allows you to quickly pull yourself backwards to an oxygen supply station – a useful way to solve complicated underwater problems.

Is your job safe? Probably not. But please don’t be alarmed! This is just another day in the office for you; it just so happens that your office is located on the ocean floor.

And remember: With your oxygen line retraction device, thinking backwards is key!

What a nice game. It could have more stages for it, since I really liked the way the puzzles are conducted and solved. Congratulations on your game.
