I have done one build challenge a few years ago with out using moo and the person is the same like you not knowing about Alt some times you'll find plants with long overhanging leaves if placed near walls will go through the wall using Alt will help not doing that with other things you wont be as creative using moo it will be like placing objects on the grid By using Alt it gives free placement without using moo try it out and see what you think if its ok to use Alt

When are you starting this challenge is there any requirements
