Revelations: The Demon Slayer attempts to bring the complex demon negotiation and fusion systems of the Shin Megami Tensei series to the Game Boy Color. Unfortunately, the handheld's limitations do it no favors—conversations with demons are frustrating, battles are a slog, and the visuals are underwhelming. Still, for die-hard Megami Tensei fans curious about this portable spinoff, it might hold some appeal.
