@LeMihkel, I like your idea. I agree with you, but I also think we should be able to choose what blocks to put certain places in the row that shows up even if we don't click more or the ->/<- arrows. That definately would save time for laggy and slow computers like mine.
You should add change gravity tool to this game... It could Change gravity for making planets with different life forms... add aliens some more insects and maybe even some more types of materials such as plastic, iron, gold, silver, copper, rotating wheel, and maybe even add a paint tool to color materials.
