For anybody thinking of following on this path, I would say it's not really worth it except as a fun hobby. I didn't keep track of hours designing/testing very well but we're almost certainly way below minimum wage on the project. Although I've learned a lot about how to make games which has been really cool. You'll make a lot more money if you don't have to manufacture a real product and deal with the high costs of freight and postal shipping. If anybody is curious you can look up "5.15 climbing card game" on google and you'll find it!
