Shiren won't hold your hand. It's the type of game that throws you into the ocean and expects you to not only learn to swim, but make your way back to shore. It's part sadism, but part respect. It's a port of an SNES game, and it shows. It's from the era where developers clearly trusted the player to be smart enough to figure things out. This isn't for everybody. This is challenge for the sake of challenge. But it's that challenge that ultimately makes the game so rewarding.
