I just finished playing the free demo (version 0.10) and it's my understanding that if I buy the game, I can only transfer that save up to the $1.80 tier (version 0.84) as it will not be compatible with the $9 final game (version 1.21). Is that correct?
Also, if I can addend questions, are the Steam version's DLCs exactly the same? And when could I expect a GOG release?
