In the near future humans have begun to study deeper parts of Earth.
They have discovered large spaces, made by unknown creatures.
In order to make a complete research a new underground ship was made.
So start your deep search and get new information.
Control your underground ship, collect items and try to explore all levels. If you collide with borders – you will bounce to the opposite direction.
If you move your ship to lava – you will lose a life.
If you move your ship to arrows – it will start slide to arow direction.
