I did a trial with c2(r90) and appMobi. The good thing is that it runs really fast!
However, I found all of my tiled bg disappeared... bg, wall, floor etc.
The touch object behaved badly. The touch end event doesn't work unless I touched another button.
For someone who has interest, here is the link. You may have app.lab installed on your device.
