Hi Greg,

The game caches all the graphics and animations when they are used for performance reasons. All of the game assets are vector graphics which are small in size but very slow to draw to the screen, when the game needs a new graphic it renders the vector graphic to a bitmap graphic which is large, but very fast to draw to the screen. The fast bitmap version is then kept in the cache so it doesn't have to be drawn slowly again. Since we have a very large number of graphics and animated characters the cache can get quite large as you play.

So in short, to make the game run fast the game keeps a lot of graphics in memory ready for immediate use which uses a fair amount of memory. (these go away when the game is closed in case that was a concern).

1.3GB of memory usage is actually not considered huge though as the average computer bought in the last 5 years has between 4GB and 8GB of memory. So 1.3GB is in the 16% to 32% usage range which for a game is not bad.

You may be still be thinking huge for a flash game, but it is important to distinguish between a "flash game" and a full sized game built and running on the flash platform.
