Sorry for no .capx.
I found something weird, when I installed my Construct 2 exported project on my Firefox OS device. Whole layout is rotated 180 degrees, but touch points are ok. For example, I touch on a sprite in left-top corner (it should show on right-bottom) and nothing happens. When I touch right-bottom corner, event attached to that sprite fires.
Could it be bug with Construct 2 or OS?
Tested on Construct 2 r152 and r155.
Project exported as Open Web App, I tried also HTML export + manually add manifest.webapp
Thanks for any help
