History Repeats Itself

Mini LD 53: "The Future is Now"

Your mission is to rescue people in the ocean, but
your ship is so powerful that the screw vortex becomes a black hole.
Avoid digging your own grave while helping people. Good luck.

Notice: vortices might eventually disappear,
but when you're crushed by a land it's immediate game over!
