Can this be used in commercial projects such as games?
Other than the art, sure. Art is subject to other licenses I mentioned in the project description.
By the way, you can also use another tool we created "Character Creator" if you need a more detailed solution. It's also free to use. Here: https://marketplace.coronalabs.com/app-templates/character-creator
By the way, if you manage to release your game, let me know. I'd love to see how it worked out for you.
