Just a bit of feed back for those who deploy to the Windows Store.
The W10 dev team seam hell bent on integrating the so-called metro interface with the desktop, which can be a nuisance and can even break some games (as in ruin game play).
Window Size Problems
The Windows8 plug used to have a Snapped mode which has now been deprecated. So now you have to use the Browser object to detect window size changes, to try to determine if the user has snapped your app, and if so pause the game.
In W10 the window by default now displays the app in reduced screen size, and you can maximize it if you want (like you don't want to run a Windows Store app in full screen - go figure!). So if your game relies on the browser object to detect window size then you are going to have to tweak it a bit.
Picture this scenario:
Game starts in reduced window (not full screen)
User then toggles full screen mode
Your game now pauses (because window size has changed)
Weird - not the desired result....
Hopefully calling Browser.RequestFullScreen will solve this. Will have to try that.....
Title and Task Bar Changes
When the mouse hovers over the top of the screen the title bar is invoked (already in Win8.1) and the game loses focus.
Similarly the Task bar now intrudes into Windows Store apps as well, so if you hover the mouse over the bottom of screen the Task bar pops up and again your app loses focus.
So if your game is fast paced and uses mouse for input, you can easily lose when the mouse hits the top or bottom (or sides depending on your Task bar position) of screen.
So Windows Store apps already on the store may be broken to some extent. Now's the time to start fixing that...
