Hello,
as the title already implies, I decided to not add Achievements to the game anymore, for the following reasons:
A long time ago Valve disabled some of the functions for games that "dont sell enough", which includes the usual Achievement functionalities. (These games carry the "Profile features limited" flag on the store-page.)
This means, you can not put these Achievements on your profile, and they wont count towards any score, even if you collect them all. (The game will not count as "completed" anymore, due to this.)
This limitation still applies to all the other ReThinks, besides the ones released before this change was made, so there is no hope for this to change.
I also dont want to add achievements "for the sake of having achievements", and therefore i wrote this news you are currently reading, as I want to be open and transparent about such things.
That aside, game will release tomorrow, no more delays.
Thank you, have a nice day.
EDIT: You can find more information about this on the Internet/Google, it is not a secret.
