The Arcade is in Beta so there are many problems.
I recently had a problem with Sprite1 on collision with Sprite2 ( a very basic event right -- I only had one of these in my game luckily so it was fairly easy to debug)
and all I got was a white screen.
When I changed to overlapping it worked.
If you want to take the time, you could dissect your game and try to load up in the Arcade in smaller pieces to narrow down the event that is causing the problem.
Here is a temp Title to use, it is the proper dimensions 450 by 300
btw, I just got a light green screen when I tried your game..
