This app crashes every now and then; it's a trial version, so to speak, so bugs or slowdowns are still very much present. But that happens rarely, so the app is still usable and functional.

This application has problems with the unknown author (export errors that I still don't know how to fix in my projects)

I would recommend reading the instructions within the app (the question mark icon in its interface)

This  is important!!!:(this game don`t have any virus and the error of creator is for a  error of export but is not dangerous!).
