I'll be honest it wasn't really fun, the tf part was just a tag, like you don't see any tf happen. and even gameplay wasn't that fun, just click button to make number biggers.
But like you said it's just a "feeble attempt to make a game economy" so I the value in it was not on the game itself but what you learn from making it. And on that your are the only one to juge!
I'm gonna follow you to see what game you'll make in the future!
