Yes that's correct, I of course understand ideally wanting those things as free updates but I think a lot of similar projects die out by doing that because ultimately there isn't much incentive for the creator to continue making content. DLC's could work but typically DLC's are not done for parts and additions that are larger or same size as the original game. Understand your feedback though and hopefully the next game being a bit bigger/longer will address some of those concerns!
PS: There is going to be one free update coming soon but I will reveal more about that in coming weeks.
