Marble Run 2D

So every time I make like a huge marble run, it just sometimes turns gray the background and I really don’t know what to do so I just save it and then when I come back to the open it back up it’s still gray developer please please please fix this glitch it already cost me eight good marble runs 😔😔😔

I mean it is fun but it’s the same with ads like 10 seconds for the other game it’s similar but 2d and it’s hard. But still buy it.

This game is very fun. You can build very big marble runs, and even get cool things from a pro purchase (I actually didn’t purchase it.) But the items included in the pro purchase can possibly help make your marble runs more amazing. But there is one problem about the game which is the glitch. When I tap or drag something sometimes the background of the game turns grey then I have to get out the game then come back in. This also undo my changes to my run that I added like seconds ago. Please developer fix the glitch so that won’t slow me down.
