Hello! Everyone will receive the build later this week - I'm finishing preparations for organising steam keys, etc.
Hi raverwild - the reason why we do testing on Steam is that way we can ensure people won't have a standalone copy of the build that they can pass around / easily hack, etc before the game is released.
We should have said in the post that the beta testing is Steam only, so I apologize for that.
Rest assured the final game will be released on itch.io though :)
