@ticacf12 Thank you for your advice, I totally agree about the UI, it needs more iterations.
About the theme, the theme of the Zanga is about "Timing", which could be implemented in a lot of different ways because it is a very general theme. All games require timing in one way or another, right :) ? You can see timing in Day-Night cycle ,where you cannot trade at night for example, and you have to time your moves so you do not get caught by Thieves. Also you have to time your actions correctly or you would miss the merchants' offers during the Day.
Thank you and good luck to all of us ;)
