how is early access going to work?

[Jojoya]

I bought the digital collector's edition and didn't manage to get one. Maybe I should login to the SE store and take a look.

For now it's just the early access code. The message I get on the SE store says the actual game code won't be release until the 2nd. Probably why the early access code works through the 5th (in case the codes are delayed in release).
