I have a smart TV running Android 4.4.4 ( https://www.kogan.co...ed-tv-ultra-hd/ ).
This isn't a touchscreen device, but it allows connecting a mouse via USB. In all other applications (both pre-installed and ones I've installed from the play store, including a number of games), mouse clicks are being recognized exactly like touching the screen on my tablet.
Except for pathfinder. It seems to ignore mouse clicks completely.
