It was one or the other.... or one of the other two game modes I get to play with before having to choose one. There where optimization problems either way, so he area has to be small, and clening an area so small would have been a two second affair. My initial idea was to make you replicate shapes more and more complex as the levels went on, almost a puzzle, but there were some many things to fix.
Thanks for your thoughts anyway, apreciated!
