Escape from colors..

Hi again!
I'm ready to share some idea about a new game i'm prototyping: "Escape from colors"!
Main idea behind that is that the player are black square flee from evil colored square: black square die if any colored squadre touch it so.. run!

Game is made with Java+Slick, as always and i'm trying to put something together to show you. I'm thinking about two main game mode:

1) time trial: survive for most time,
2) level mode: survive for 60 seconds in more and more difficult levels,

Some screenshot soon!
