nft game development

We'd like to use https://phantom.app to allow game developer & game user do Solana transactions, as in this case they don't need to provide Solana wallet private keys, but only phantom wallet password. There is no way as we know so far (we'll talk to Phantom wallet devs about it) to integrate phantom wallet anywhere besides browser extensions. So we'd like to:
* For a game developer - connect Phantom wallet for creating new NFTs in the Unity IDE
* For a game user - connect Phantom wallet for buying NFTs in the game
* Phantom wallet will ask for transaction confirmations for both cases

https://phantom.app
In the future we'd probably want to have a choice between Phantom Wallet or SolFlare wallet for users, but the idea is the same w/ SolFlare as it's just browser extension as well

I would need to understand how you would approach this.
