10 New Levels!

This update brings 10 new levels to the game and a couple of new features including keys and locked paths and different colored blobs, which have different properties.  Oh, and there's a big blob on level 20.  Defeat it to get your coins.

I hope you enjoy the game.  Please let me know what you think in the comments.

Oh, and if you find anything weird, please let me know and I'll do my best to fix it.  I'm just one guy building and QAing this so I'm sure I missed something.  

Thanks!
