Hello, itch people. (Itchers?)

I'm working on a roguelike WebGL game, and it would be very useful for me to get some details on choices my players are making. Has anyone ever hooked up a game on itch into more detailed analytics? To be clear, I'm not looking for data on who is visiting the website (itch.io does a good enough job for that), but rather in-game how players are choosing Perk X over Perk Y, how long a typical game lasts, etc. I hope to use that data to make a more compelling experience.

I'm building the game in Unity, and I know Unity has some good data gathering tools. Do they work easily with Itch.io? Does anyone know of any tutorials or other places to get started?

Thanks,
Josh
