Hi, i changed the engine to "standard web-based".
Now the game starts, but crash after 20 seconds.
Whatever layout i choose for start (also a blank layout), the game it crashes after few seconds and runs at 5fps or less!!
In the debug warnings i have got this error: "Not found getElementbyId: c2canvasdiv"
I've installed r144.2 and now r145. Problem not solved.
