Iruka Iru Ka is a japanese word pun turned into a game.
Somewhere in these caves there is a dolphin. It is up to you to find it deep into the deep hollow cave.
But you have a limited air supply, unless you can find that dolphin before the time is up it's game over! You have 3 beacons you can deploy per level to help you mark areas, as well as extra time pick ups.
