I’m not familiar with the Hamtaro manga/anime, which has a target audience of tween girls but evidently has fairly widespread appeal. The game sold well in Japan, and Nintendo had enough faith in it to release it in America and Europe. It looks like the GBC BIOS adds about 185 frames, and so the total improvement should be about 350 frames. There is not much to say about the gameplay. Most of the game consists of hamsters talking to each other. Not that it’s trivial, it’s just lacking action. The hamsters are large and cute. But otherwise the game seems like a small step forward from Zork. Previous entertainment ratings are fairly low. People who are into it tend to like the big innocent eyes and winsome language rather than the actual game. It should stay in the Vault.
