I tried your app and I guess that your problem is that you don't properly describe what it is about. You don't describe it in the play store, you don't describe it within the app, and I bet you didn't describe it in your add. What people saw on Facebook was an add for a "new game". Well...
As for the game itself: the one you copied it from is bad in my opinion. It's based on luck."Press until a proper shape starts to form, then continue pressing.". Yours is the same but less polished.
Good luck.
Infinity Loop: BluePrints is another puzzle game is quite popular and I love it
