Fixed the bug related to the spawn of the rocks

Dear players,

After we got some more feedback from a few of you, we are able to notice some bugs. We just uploaded this morning a new version. 

Now the stones won't spawn into one another or in bottles creating this effect :

We also noticed that some collisions on the can in the center were counted in the reduction of the score when they shouldn't have, we fixed that as well.

In the next patch, we will fix a bug there is when multiple collisions are counted when there is supposed to be only one. 

Hope you keep enjoying our game!

Don't forget to rate it if you have a minute, it would help us a lot :)

Have a nice game!

Charlie and Clément
