laws about analytics dramatically worsened
Oh, you mean it is better for anyone to be able to gather any data for any reason without telling and doing with that data who knows what?
I am curious, what exactly could data tell you to improve the games. You sure you are creating a game that will benefit from the type of data analysis that Unity promises? They are selling a service there afterall. They are optimised for games with thousands of players and advertisements or micro transactions. It is about making more money. But for that you need to have something to be optimised.
So, do you think you will have a game with thousands of players that is a cash generator with optimisiation potential? If so, you will also have the funds to get professional legal council. Aren't you with a publishing group? Do they not have that knowledge?
Anyway, Itch cannot provide you with things it does not collect. They can only provide data about how the files are downloaded and data about referals. But they cannot provide data about how the games are played - which is what Unity would do.
The game on your profile pages's image is published January and has 1 review on Steam, despite looking quite professional and enticing for the target audiences. Imho you do not need data analysis, you need marketing.
