I went through the whole effort of creating account and was able to play the game. Not really clear what the goal was. But I can imagine it was pretty much work to get it integrated with wallet systems.

The main point of the game was so that you can save your game on the blockchain. Making a character as an NFT removed a lot of dependencies like not being able to play when a game server is down ( As it is basically impossible to stop a big blockchain), Stops cheaters from messing with their characters ( Because all the character logic like leveling up is done by a smart contract and only coding errors could lead to exploits) and trading any game asset with people is a lot more secure (Wish I had more time to write a smart contract for items it would have been a lot more fun)
