C&VG refers to the game as "Super Shinobi II", which is the Japanese title. The reviewers praise the graphics and sound, but aren't as happy with the gameplay, stating it being too similar to the first one. The screenshots show various rounds, including some areas which are in the first prototype, but a lot which aren't. The screenshot of the Hakuriu ninjitsu shows large and small ice crystals all over the screen, and the review itself states that the attack freezes all enemies on the screen for a short amount of time -none of the other magazines say this is what it does.
