Version 0.0.7 smoother gameplay update

I spent a lot of time today reworking the way the blocks get destroyed, how collisions and physics works in the game, adjusting the particle systems and making sure level 10 is beatable.  I'm really happy with my progress so far and I'm really starting to get a handle on the "proper" way to do at least the basic stuff in Godot engine.  Really enjoying the experience so far! Let me know what you think.  

I appreciate any and all support be it bug reports, comments, suggestions, complaints or monetary if you could spare it!
