Scratch

Have you ever played the PixelJam games Ratmaze or Ratmaze 2?  Well, now there's a pretty accurate rendition on Scratch!  Although the game itself is a fun and extensive maze (even including a secret room!), one of the best parts is the encouragement to remix.  The game operates on a coordinate system for the current "room" of the maze.  This system is simple to learn and apply, making it an accessible and cool remix to make your own maze!  Have fun eating all the cheese!
