The game is an attempt at a mini-crossover with Sailor Moon, in which characters from that universe can be summoned by Sonic and his friends as helper characters with the use of Chaos Emeralds. It takes on an 8-bit Sega Master System style and is designed to look as authentic to the system as possible (I think).
