I don't understand why you don't create a testnet where you can play the game with free testtokens. That way players can test the game without spending money and players can also find glitches that can't appear in the real game. All NFTs and tokens would be free in the testnet and as an incentive for testers you could drop a reward for the 10 best players once a quarter.
Have you already discussed this idea internally or is this a stupid idea of mine?
