Nice!
Ok, a suggestion: How about a game with a story and obstacles?
Example:
1. Your mouse-girlfriend have been caought by the evil mom, and now shes keeping her in a jar, and you have to resque her...
Maybe a big square, with obstacles, such as mouse-traps and slippery kitchen-oil, and sticky glue and stuff... I would be thrilled to play a game like that ^^
Tell me if you'd like any help with it
