Thanks for playing my game and the constructive feedback!
The indicator is definitely at the at the top of my list of things to update in the future.
The Ui shows how many resources you have and how expensive each building block is. But I guess it's not obvious enough, so that's something I need to change. The UI is too big, so there's also that haha.
A tutorial would have been great, but sadly, I didn't have time. But I definitely plan on adding one.
Again, thanks for the suggestions!
