Sonic the Groundhog Day

A game very like Sonic the Hedgehog, but with only three levels. The player character is a groundhog rather than a hedgehog. The first level is a dull, wintry level where the player not only accumulates powerups but is supposed to woo a love interest character like Amy in Sonic. The level repeats itself over and over again until the player succeeds with the Amy/Andie McDowell character, with only one other difference in the level. Randomly, half the time the groundhog's shadow is visible throughout the level, the other half it isn't. If the level is won when the shadow is visible, the next level has a snowy theme. If the shadow is invisible, the next level has a springtime theme.
For the duration of the game, the computer's/console's date is set to the second of February until the level is successfully completed.
