*DISCLAIMER* if you are wanting to sell the games you make find another software. This app is great, not perfect.
THE CONS
The flaws are you can not make to long of a game with out it lagging, no custom music, no custom sprites and and not to much to choose from.
THE PROS
Everything else in the software, and there is A LOT in the software :)
