Don't worry, there's a lot of wiggle room on choices like relationships (like the thresholds for stuff is like half the maximum you can get). You can't ruin the relationship either. High affection and low affection will branch into different paths. So you're not missing out if you don't get high affection, just changing which branching path you'll take with their side quests later. For Liebra... all in good time. I intend for most things to be clear by the end of the game.
Thanks for the kind words! I'm happy you've been able to enjoy it.
Thanks for the quick answer there you didn´t say now to romance I will asume there is yeah I really like Harper she seems really nice but is also cool and has fire. Another question when you publish chapter 7 someday ( I don´t want to push you take all the time you need to make this perfect) do I have to do something like download the game again and if so do I have to replay everything again because I am sure how this would work with my progress on my computer
I'm mention in the patch notes if saves ever break. I try to not break saves when possible. And, at most, I expect it to happen maybe once before the end of development. But hopefully just that once.
For downloading, yes. Any release with a v#.#.0 involves new content+assets, and will have assets you need to download to continue the game. It's a mess logistically to try and make patches in these cases since its so situation dependent, so the game files need to be downloaded. You can then move your Save folder over to the new files
For romance, it depends on the character (will be open that Harper specifically has no romance content planned. That connection is more familial like)
