I need some help with the pen tool

I'm trying to make a 3D game on snap but when i create my "model" I see the whole wireframe. When using the fill command it doesn't fill properly.

Does anyone know a solution to this?
here's the project link

I'm not sure there's an easy solution, unless shape-fill is added to Snap!.

not sure if this helps any but this is the best ive ever gotten. still not great, dark background helps


I did a quick test, but it's not effective...

I make a costume from the individual drawing of each of the faces that I store in a variable, then I stamp all the costumes...

Oh thanks for the feedback! I'll look into into it and try to find a solution.
