I've tried this for very short time but I love it, the way to create the levels is super intuitive, the only con that I see is that I can't export my own levels as exe, as it comes inside your game. I know that maybe this is not of your interest but I wish if you could make that you could make your own platformer game with this like RPG Maker and you can export as exe. Even if you only give permission for non-commercial purposes and giving you credit and pointing you as the original game.
Very awesome anyway, friend!
