Baby Taylor Build A Treehouse

Baby Taylor Build A Treehouse is one of the Girls games here that asks for no download and no sign-up. Designed around touch input, and comfortable on a small screen. Its tags here are baby, cute, decorate, design, educational.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Everything runs client-side, so there is nothing to set up before you start.
