Wow! that was unexpected. I didn't really expect that you're going to hear out my opinion. Thanks for adding that option to login, I would now give a try to your game and will give my feedback later on.
I really like the concept but my question is the same as many, How is revenue being generated to keep the game sustainable ? I think a referral program is needed to get players. I could easily get a few hundred people playing within a month but there is no incentive for me to do so.
They are starting out and most start ups has their own budget to start to sustain their rewards. And after that, once the game clicks there will be advertisers and revenue will start coming in with various sources.
