Pretty satisfying puzzle once you learn the rules! I got confused by the UI at first, I didn't understand why zooming or dezooming didn't have an effect on the house I was holding, and so I wrongfully assumed that their height was fixed. It is also possible to soft-lock once you have placed too many houses and don't have any space left.^^' But I was more cautious at my second attempt, and the experience was a nice memory test and space management challenge!
