Ikachan is a short side-scrolling adventure game from Pixel, the man that single handedly developed Cave Story. In Ikachan, you are a small squid-like creature which the game is named after, who has found himself in an unfamiliar area of the ocean and must work with its denizens to find a way out. Ikachan can swim around, and attack foes by thrusting and piercing them with his head.
