Draw on a Block will be available on Steam tomorrow - March 2nd - at 1pm EST. Not too long after release, I will begin releasing additional model kits, starting with the house kit. It will include structure and furniture pieces for every room.
For this first piece, I wanted it to be clean and simple. I decided to keep it low res, just painting the edges and using the built-in blur tool. You can change the resolution in-app and paint it however you like.
Also, you can import any model you create. There is also a built-in UV unwrapper that works well if your model is sized for the pixels per units you want to paint.
