I can sum this review up in only four words: Sonic the Hedgehog Ripoff!
While this game is okay... if you've never played Sonic the Hedgehog, no one can deny that this is nothing more than a cheap knockoff of a much more successful - and classic - title.
This might be overlookable if the game itself were actually fun to play. Well, let's just say... the bar was set really really high by Super Mario RPG, but hey, let's try and review the game on its own merits, shall we?
In that case, what's my goal? I mean, the opening cinematic seems to imply that the objective of the game is to rescue all the other mice. This goal seems to be confirmed at the beginning of each level, where it tells you how many mice there are in the level, and some of them even say that I need to rescue these mice, but it hardly seems to matter. It seems that the only real goal is to get to the end of the level without dying, which is an okay goal, in and of itself, but it seems totally inconsistent with the story involved.
If the game required me to get a certain amount of mice, and then, it would open the door to the next level, that would be okay, but why would you give me a main objective that I don't need to complete?
Rescuing mice only seems to matter for getting a high score, although a high score is rather pointless. For one, this isn't the Atari 2600; the days of gamers caring about high scores are over. Second, the game doesn't save your high scores, so it's kinda pointless to actually do it.
Speaking of saving, not only does the game not save your high scores, but it doesn't save ANYTHING! First of all, saving your data via battery-backed memory became the new standard on the friggin' NES, with the Legend of Zelda! Second, if they won't give me a save feature, couldn't they at least have the courtesy to give me a password system, so I can return to a later level as soon as I fire up the system? As it stands, you have to complete the entire game, from start to finish, in a single sitting. If your mother calls you down to dinner, either you pause the game and run the risk of your SNES overheating, or you have to turn it off, and, when you're done eating, you go back to square one!
If they had fixed these two problems (lack of an actual goal, and the inability to save your progress), this game might actually be something more than a cheap Sonic the Hedgehog ripoff. As it stands, however, this is worth a rent, but not a buy.
