Aweful! I should have read the reviews before downloading. I have never downloaded this game before finding it on another game wall. The game offer was to provide gems to that game for unlocking the "Santa Cruz" level in this game. I completed this and met the condition to receive the free reward. However, I was denied the reward because I had "previously downloaded this game". This is entirely untrue. I will be avoiding ALL products from this company and group of companies in the future.
