Yes that is understandable, we will definetely add a tutrorial as pretty much everyone had the same issue, need to make it more intuitive.
Umm so the issue we did think of something of progressing based on the player, but couldn't think of anything to add to make it difficult to balance, was mostly thinking of making it in a tycoon based game but I think my hopes were too high as its the first game I have worked on.
