LÖVE

I have 3 questions:

1. Has anyone tried to publish a Love game to Windows Store?

2. What about your game total downloads count, is Windows Store have larger or smaller market share than Google Play/Appstore ?

3. Is it worthy to publish my game on Windows Store (despite falling WinMobile market share, but I think Win10 Desktop market share stil huge) ?

If you're talking about LöveFTW, the Löve port to Windows Apps, then no, as far as I know no games have been released on the Store. The UWP version is still not finished (and development is more or less abandoned for now).

Yes, I know the development of LoveFTW seems to be dead now, & the recent Windows Phone device sales went downhill.

I only interested in Windows 10 Desktop. I think there's huge potential in Windows Store as I can upload Love game as native Win32 program (but run inside sandboxed virtualization / Microsoft App-V).
