Alison and Colleen: All You Need is Summer

Alison and Colleen: All You Need is Summer is a promotional Game Boy Color game released in 1998 to coincide with the release of the film of a similar name.

Gameplay
You get to wander the abandoned playground (set in a top-down point-of-view) and you could select any stage you want. The stages are side-scrollers that require you to take out all the bad guys and collect certain items.

Release
While the game received a commercial release, it was primarily sold at McDonalds where people would have to buy them individually.
