A notable departure from the arcade-style action of its predecessors, the sole Game Boy Color installment is more of a puzzle platformer, and was developed by a company called Biox. (It’s also remarkably similar to Samurai Kid, another title by the same developer.) Each stage is fairly large and filled with enemies and minor obstacles, as well as keys to find. Gen has three different types of enemies – one will kill enemies, one will turn them into blocks, and one will anger them so they’ll follow Gen around the screen. With this in mind, you use these tools to turn enemies into blocks and utilize them to hit switches or springs. Gen can also use his hammer to climb onto platforms, hop on like a pogo stick, or use as a umbrella to control his falls. Even though it’s pretty ugly, it’s actually a nice little diversion.
