Well, me being paid for my work so I can keep doing it, is kind of fair I'd say. So apologies for not giving all my work for free.
I didn't meant that for christ sake. I meant saving feature being disabled, which I think is first time hearing that. Like...does Auto Save work at all? I understand if you are doing that because free version you gave is the same version you need to pay for, I understand why you disabled the saving feature. Doesn't change that it was a surprise.
Saving features have been disabled for a while now, including all the old demo versions. This version difference is that it unlocks everything else and updates all to the latest patch.
It's on the Free game page info, it's on the official post, and it's in the bottom right of the screen while playing, so it didn't come as a surprise to the player.
Disabling saving on demo and trial products is very common.
