A successor to the Dutch studio's earlier Amiga game Hoi, Moon Child stars the titular green elf, who is sent to the planet Utopia from its moon to save it from a techno-virus. To do this, he must scour each level for Dark Diamonds that are hidden in various places.
The game was originally planned to be developed for the Amiga, with a demo version released years earlier. Due to Commodore's bankruptcy, the game was shifted to Windows PCs. This version includes Hoi as a companion character, a concept that was later removed.
