Ikachan is an adventure game developed by Nicalis and released on Nintendo 3DS. You wake up in an underwater cave. Near the bottom of an enormous abyss, there's only one way out. Swim in a dark world under attack by frequent earthquakes and famine. This vast undersea kingdom is filled with both dangerous and hamless denizens. Its fearful inhabitants are led by a reluctant fish who has no answer to the impending disasters.
Take to the sea and help your new friends flee their home and find a new one. Their fate rests with you, Ikachan. You must help them find a way out before it's too late. Use whatever tools you can and try to escape. Swim, Ikachan, swim!
