I'm on Linux, so I can't test the actual app. However, I'll say that the website didn't feel very clear about what the app is supposed to do. My first assumption was that this was a game engine. After glancing over the first page, I saw it depends on Corona. I had never heard of Corona before. (I'm slightly more familiar with PC gaming than mobile gaming.) My next thought was "Which of these two things is the game engine, and what is the second one?" I had to Google to find out what Corona does. From what I gather, Corona is a Flash-like compatibility layer over iOS, HTML5, and Android. Your app seems to be a sprite editor that exports to Corona. Apparently neither one provides a full game engine. Is that correct? Whether I'm correct or not, I would recommend updating your site so that people can find that out without having to dig like I did.
