Love it, buuut a few suggestions...

I love this game, but on mobile i cant share my creations with the world. And also there should be a 2 player thing where you can control two "players" at the same time. There should also be a thing so you can see glass. I know you can use toon setting but it is not very effective. You should also add more powders.
I had more ideas, but i cant think of them at this moment.
