I like the game through and through, and I think it has some potential for growth! I've been playing for a few days and I'm about half way through earning what you can for free. It would be hard to earn enough ingame money to be able to buy an nft, but you can earn nfts. If you're hoping to earn something of decent value for free, best get started ASAP, in my opinion anyways.
As far as gameplay goes, I just wish it was easier to choose specific game modes to play instead of cycling through the 3 types of gamemodes there are.
