You'll get a chance pretty soon: we are releasing absolutely free Lite version. It shall happen within the next 5 days, we are waiting for AppStore review. It will has no monetization at all - 100% free version just to show the game concept and what we have done already.
That sounds good, if you have a promo code or test flight download I wouldn't mind trying that as I believe the codes let you get the apps early.
You will not need any code, the game will be opened for public download right in the moment when it will be approved by Apple. We expect it to happen in couple days.
