I see.  I have nothing to do with the app.  I can confirm that my game will not launch on that app, and I get an error, but I'm not sure I have the technical programming skill to solve the problems a third party application is having when it attempts to run my game.

It doesn't quite sound like the issue you're having is the same as mine.  I haven't seen my game fail to install in the app, only fail to launch.  So, I'd recommend reporting your issue with the app to directly, as it's clearly their program creating the problem with my game.  However, I see no reason why the game wouldn't download and install correctly from the website, as intended.

I've also reached out to to find out why their app won't launch my game, and I've included your issue as well, but the fastest solution is just to download the game from the website and install it normally.  Otherwise, we'll just have to hope they respond quickly with a solution.
