Thanks for the feedback. In the beginning I wanted the progression to make sort of a "logical" sense. Like if you have wood, you can make a log cabin or something like that. But I quickly found I was limited by the Kenny Assets on hand for this particular game jam - and then I didn't have enough time to make something that previewed the materials needed. So I think if I was to take it further I'd consider both options. I appreciate you well thought out comment and for playing my game!
