This is really great! Spent a few minuted getting my head around it and i'm already making simple scenes. Will dive in more :)

Immediate thoughts were "Wow, well then..."

Interesting layouts with current type and colours. I'd say that there might be a few to many font sizes in such a little space. Maybe a bit more spacing / white space (especially above the fold), but loving the direction!

What did you build it with?

Good pallete and balance. One thing that jumped out, the first mobile mock-up is missing a part that should be visible. Keep it up :)

Looks great. But you still have to edit code / links from what I can see, would changing that content in the app not be more helpful?
