I recently released a project called Francois DIY - my version of Mario Maker and I am in the process of making levels. Playing my own levels is fun but playing other people's levels is even more fun! Anyways, this is more of a want than a need but I'm starting to get addicted to Francois DIY and Mario Maker!
