I created a demo app for UWP and uploaded it into the store:https://www.microsoft.com/en-us/store/games/wmelite-engine/9nblggh4wb5z
It is based on my branch of WMElite. Should work with both mouse & touch input.
I made a deviation to the user interface, a short click/touch will invoke the "look action", and a long mouse click/touch will show the overlay menu.
Source code is on bitbucket. Feedback welcome.
