An earlier platformer by Cave-Story-maker Pixel, that sports some RPG elements, unlike his more famous successor. You are a little water creature (something squidlike, I think) that can propel itself forward by bubbling out of its underside. You can only move sideways or upward, if you want down, you have to let yourself sink to the bottom. Enemies get beaten by head-butting them, and you get experience for each kill, as for collecting fish items. Your mission is to evacuate all the denizen of a little pocket of the sea, before it caves in. Ikachan isn’t a long game, but for those few hours you probably take to complete the game, it’s great fun.
