[2020] Will it be possible to back the game for CA access post-release?

I've been following this game and it's developers for the past 1-2 years and am only growing more excited to see its first public release, but I'd like to see some gameplay by the community before I back it myself.

So, will it be possible to gain access to the CA by backing after it has already released? Will the Indiegogo remain open? Cheers guys.
