Koma, or Beigoma, are a kind of traditional Japanese wooden spinning top. In this game, you play as one in the odd situation of having to collect exclamation marks while trying to stay to moving platforms above an endless black void. Each stage has a different set of platforms, and though they move in the same patterns every time, the exclamation marks appear in random positions.
In this doujin arcade action game by E. Hashimoto, you play a warrior tasked with defeating the great evil of his land. Jump, slash, & dash across five increasingly difficult levels, each with secrets & bosses! Originally made for the Sharp X68000, Hashimoto would later remake the game for Windows in the 2000s.
